Love is a constellation of emotions and experiences related to a sense of strong affection or profound oneness.^[1] The meaning of love varies relative to context. Romantic love is seen as an ineffable feeling of intense attraction shared in passionate or intimate attraction and intimate interpersonal and sexual relationships.^[2] Though often linked to personal relations, love is often given a broader signification, a love of humanity, of nature, with life itself, or a oneness with the Universe, a universal love or karma. Love can also be construed as Platonic love,^[3] religious love,^[4] familial love, and, more casually, great affection for anything considered strongly pleasurable, desirable, or preferred, to include activities and foods.^[5][2] This diverse range of meanings in the singular word love is often contrasted with the plurality of Greek words for love, reflecting the concept's depth, versatility, and complexity.

The definition of love is the subject of considerable debate, enduring speculation and thoughtful introspection. The difficulty of finding a universal definition for love is typically tackled by classifying it into types, such as passionate love, romantic love, and committed love. These types of love can often be generalized into a level of sexual attraction. In common use, love has two primary meanings, the first being an indication of adoration for another person or thing, and the second being a state of relational status. Love is an act of identifying with a person or thing, capable of even including oneself (cf. narcissism; reverence). Dictionaries tend to define love as deep affection or fondness.^[1] In colloquial use, according to polled opinion, the most favored definitions of love involve altruism, selflessness, friendship, union, family, and bonding or connecting with another.^[6]

love in various scholarly publications as acting intentionally, in sympathetic response to others (including God), to promote overall well-being. Oord means for his definition to be sufficient for research in ethics, religion, and science.

The different aspects of love can be roughly illustrated by comparing their corollaries and opposites. As a general expression of positive sentiment (a stronger form of like), love is commonly contrasted with hate (or neutral apathy); as a less sexual and more mutual and "pure" form of romantic attachment, love is commonly contrasted with lust; and as an interpersonal relationship with romantic overtones, love is commonly contrasted with friendship, although other connotations of love may be applied to close friendships as well.
