The 7 types of love: from ancient Greece to modern psychology

English has one word for love. This is a problem.

We use the same word for the electric obsession of a new relationship, the steady warmth of a 30-year marriage, the fierce protectiveness we feel for our children, and whatever we mean when we say we love pizza. Greek had at least seven words. They understood something we keep tripping over: these aren't different intensities of the same thing. They're different things.

Modern psychology arrived at the same conclusion through a different route. When researchers tried to study "love" as a single construct, the data wouldn't cooperate. What predicted satisfaction in new couples failed completely in couples married for twenty years. The brain scans looked different. The behavioral patterns looked different. They weren't studying one phenomenon. They were studying several, all sharing a name.

What are Sternberg's seven types of love?

Robert Sternberg, a psychologist at Yale (and later Cornell and Oklahoma State), proposed his Triangular Theory of Love in 1986. It remains one of the most cited frameworks in relationship research. His argument was straightforward: love has three components, and different combinations produce different experiences.

The three components are intimacy (closeness, connectedness, bondedness), passion (physical attraction, romance, sexual desire), and commitment (the decision to love someone and maintain that love over time).

Each component can be present or absent. That gives you seven possible combinations, plus the absence of all three.

Liking has intimacy alone. It's genuine closeness without passion or commitment. Deep friendship. The person you'd call at 2 AM but have never wanted to kiss.

Infatuation has passion alone. Pure attraction without real closeness or any decision to stay. The stranger on the subway you can't stop thinking about. Sternberg noted that infatuation can arise almost instantly and can dissolve just as fast.

Empty love has commitment alone. The decision to stay without intimacy or passion. Some arranged marriages start here (and many long-term marriages end here). It sounds bleak, but Sternberg pointed out that it can be a starting point rather than an endpoint, particularly in cultural contexts where commitment precedes emotional connection.

Romantic love combines intimacy and passion without commitment. It's the intoxicating early phase of many relationships. Physically drawn to each other, emotionally close, but no promises made. This is the type that dominates movies and pop music, which is unfortunate, because it's inherently unstable. Without commitment, any disruption can end it.

Companionate love combines intimacy and commitment without passion. Close, bonded, in it for the long haul, but the physical spark has dimmed or disappeared. Many long-term marriages settle here. Elaine Hatfield and Richard Rapson at the University of Hawaii studied this transition extensively and found that companionate love was the strongest predictor of relationship satisfaction after the first two years.

Fatuous love combines passion and commitment without intimacy. Whirlwind marriages. Intense attraction and a quick decision to commit, but without the deeper knowing that comes from real emotional closeness. Sternberg identified this as the most fragile combination because the commitment rests on passion alone, and passion is the most volatile of the three components.

Consummate love has all three. Intimacy, passion, commitment, working together. Sternberg described this as the "complete" form of love that many people aspire to. He also noted that it's harder to maintain than to achieve. Reaching it requires effort. Keeping it requires more. The relationship between being in love versus loving someone maps directly onto this framework.

What were the Greek types of love?

The Greeks didn't have a single unified taxonomy. These categories come from various philosophical texts and common usage across centuries. But they captured real distinctions that modern research has largely confirmed.

Eros is passionate, erotic love. Named for the god of desire. The Greeks weren't sentimental about it. Plato discussed eros as a powerful force that could lead to either transcendence or ruin, depending on how it was directed. It maps roughly to Sternberg's passion component. The Greeks treated it as a form of temporary madness, which, given what we now know about the neurochemistry of early attraction, was remarkably accurate.

Philia is deep friendship. Aristotle considered it the highest form of love, writing extensively about it in the Nicomachean Ethics. He distinguished between friendships of utility (you're useful to me), pleasure (you're fun), and virtue (I admire who you are and want the best for you). Only the third type, he argued, counted as real philia. It's slow to develop and requires mutual respect.

Storge is familial love, the affection between parents and children, between siblings. It's the quiet, assumed bond that doesn't require constant renewal. You don't earn storge. It exists by virtue of shared history and kinship.

Agape is unconditional love, selfless concern for another's well-being regardless of what you receive in return. Early Christians adopted this term extensively. In psychological terms, it aligns with what researchers call communal orientation, described by Margaret Clark at Yale as a focus on the partner's needs without expectation of direct repayment.

Ludus is playful love. Flirtation, teasing, the early giddiness of mutual attraction before anything gets serious. The butterflies. John Alan Lee, a Canadian sociologist who built on the Greek categories in his 1973 book The Colors of Love, positioned ludus as a game-like approach to romance.

Pragma is pragmatic love. The love that develops through long-term effort, compromise, patience, and tolerance. It's what's left after the passion fades and is replaced by something quieter but more durable. Lee described pragma-oriented lovers as those who approach relationships with realistic expectations and a willingness to work.

Philautia is self-love, and the Greeks split it into two forms. The healthy version (connected to self-respect and self-knowledge) enables love for others. The unhealthy version (narcissism, self-obsession) destroys it. Aristotle argued you couldn't genuinely love another person without first having a settled, honest relationship with yourself.

How does Lee's "Colors of Love" compare to these frameworks?

John Alan Lee deserves more credit than he typically gets. His 1973 work, expanded in 1988, proposed six love styles that combined the Greek categories with empirical observation. He framed love styles as orientations, not types of relationships, meaning the same person might express different styles in different relationships or at different life stages.

Lee's primary styles were Eros (passionate), Ludus (game-playing), and Storge (friendship-based). His secondary styles were combinations: Mania (Eros + Ludus, obsessive and possessive), Pragma (Ludus + Storge, practical and list-driven), and Agape (Eros + Storge, selfless and all-giving).

Clyde Hendrick and Susan Hendrick at Texas Tech developed the Love Attitudes Scale based on Lee's framework and tested it across large samples throughout the 1980s and 90s. Their findings were consistent: Eros and Agape orientations correlated with relationship satisfaction. Ludus correlated negatively, in both men and women. Mania predicted instability and distress.

The practical takeaway from Lee's work is that people approach love differently, and those approaches matter more than most people realize. If one partner has a pragma orientation (practical, list-driven) and the other has an eros orientation (intensity-seeking), they may love each other deeply while constantly feeling like something is off. Neither is wrong. They're operating from different frameworks.

Which type of love predicts long-term satisfaction?

The research converges on this point. Hatfield and Rapson's decades of cross-cultural work consistently found that passionate love (eros, infatuation, Sternberg's passion component) peaks early and declines. This isn't a failure. It's biology. The neurochemical cocktail that drives passionate love, dopamine and norepinephrine flooding the reward system, wasn't designed to last indefinitely. Helen Fisher's brain scanning studies at Rutgers confirmed this trajectory in 2004.

Companionate love, built on intimacy and commitment, predicted satisfaction at 5, 10, and 20 years into relationships. Couples who maintained high levels of companionate love reported greater life satisfaction, better health outcomes, and, perhaps counterintuitively, more frequent sex than couples who chased passionate love but lacked the friendship foundation.

But there's a nuance. A 2011 study by Bianca Acevedo and Arthur Aron at Stony Brook scanned the brains of people in long-term relationships (average 21 years) who reported still being intensely in love. The scans showed activation patterns similar to early-stage romantic love, with one key difference: the anxiety and obsession circuits were quiet. They had intensity without the instability. Passion can persist in long-term love. It just looks different from the early version.

The stages of a relationship tend to follow this arc: passion-heavy at the start, transitioning toward companionate love, with the possibility of a mature form of passion reemerging once the relationship is secure.

How do types of love shift over a relationship?

Every long-term relationship is a sequence of different loves wearing the same face.

The first months are typically dominated by eros and ludus. High passion, playfulness, idealization. Sternberg's intimacy component is often experienced as rapidly increasing closeness, though much of what feels like deep knowing at this stage is actually projection. You know the version of them they're showing you, which is the version they think you want.

Between one and three years, intimacy deepens as idealization fades. You see each other more clearly, including the parts that are hard to accept. Passion typically begins its decline. This transition is where many relationships fail, not because anything went wrong, but because people interpret the shift as evidence that love is dying rather than changing. Understanding this as a natural evolution rather than a crisis is one of the most useful things the research offers.

In established relationships (five years and beyond), commitment becomes the structural foundation. Companionate love dominates. Couples who maintain active curiosity about each other, who keep updating their understanding of who their partner is becoming, tend to sustain higher levels of intimacy. Those who coast on the assumption that they already know everything about their partner see intimacy erode. Aron's self-expansion research at Stony Brook showed that couples who engaged in new, challenging activities together could reactivate some of the dopaminergic reward patterns associated with early love.

The couples who fare best seem to be the ones who accept this evolution rather than fighting it. They don't mourn the loss of infatuation. They invest in what companionate love offers: genuine knowing, reliable presence, shared meaning. And they find ways to inject novelty and playfulness without expecting it to feel like month three again.

What type of love are you actually looking for?

Most people say they want passionate love. Most people who've been in long-term relationships say they're glad they found companionate love instead. There's a mismatch between what we think we want and what actually makes us happy, which tracks with decades of affective forecasting research showing that humans are reliably bad at predicting their own emotional futures.

If you're in a relationship right now and you're reading this because something feels like it's missing, ask yourself which component has shifted. Is it passion? Intimacy? Commitment? Knowing which type of love you're experiencing, and which you're craving, is the first step toward an honest conversation with your partner.

Aperi's daily questions are designed around this idea. Different questions target different components. Some rekindle curiosity (intimacy). Some spark playfulness (passion). Some ask you to recommit. One question a day, mapped to where your relationship actually is, can help you and your partner figure out what kind of love you're building and what kind you want to build next. You can also explore question packs organized by relationship depth and theme.

Frequently Asked Questions

What is the strongest type of love?

In terms of long-term relationship satisfaction, companionate love (intimacy plus commitment) has the most empirical support. Hatfield and Rapson's cross-cultural research consistently found it outperformed passionate love as a predictor of relationship quality over time. That said, Acevedo and Aron's 2011 brain imaging study showed that passionate love can coexist with long-term stability when the anxious components are absent.

Can you experience multiple types of love for the same person?

Yes, and healthy long-term relationships typically involve exactly this. Sternberg's model predicts that the balance of intimacy, passion, and commitment shifts over time. The same relationship might start as romantic love, transition through companionate love, and develop elements of consummate love. The Greek types can also coexist: eros and philia and pragma, all present at different moments.

Is passionate love always temporary?

The intense, anxious, obsessive form of early passionate love does tend to decline within 12 to 18 months, based on Fisher's neurochemistry research. But passion itself isn't necessarily temporary. Acevedo and Aron found couples married over 20 years who showed brain activation patterns consistent with intense romantic love, minus the anxiety and obsession. The passion evolves rather than disappears.

What does it mean if I love my partner but I'm not "in love" with them?

This usually means the passion component has diminished while intimacy and commitment remain. By Sternberg's framework, you've moved from romantic or consummate love to companionate love. This isn't a death sentence for the relationship. Research by Aron on self-expansion suggests that shared novel experiences can reactivate passion circuits. The distinction between being in love and loving someone gets a deeper treatment here.

Which Greek type of love is most important?

Aristotle would say philia, and the research tends to agree with him. Deep friendship, specifically Aristotle's "friendship of virtue" where you genuinely admire who the other person is, forms the foundation that other types of love build on. Gottman's research found that friendship quality was the single best predictor of relationship satisfaction across his longitudinal studies.
