An unanswered infatuation can occupy a mind for years

Limerence names what love and crush blur together

"He doesn't know I exist, but yes I love him with all my heart." One of the women in Dorothy Tennov's research said this about a man who had no idea how she felt.² Tennov, an American psychologist, spent the 1960s and 70s gathering cases like it. Thousands of questionnaires, autobiographies, and case histories all described the same involuntary, intrusive infatuation.³ Ordinary talk of "love" or "a crush" flattened that infatuation into something calmer than it was. She published the pattern in 1979, in a book titled Love and Limerence: The Experience of Being in Love. The name existed so the state would stop hiding inside a word that also covered its opposite.

She built the word to carry no history

Tennov's first candidate was "amorance," built plainly from the Latin word for love.⁴ She dropped it for "limerence," a word she said flatly "has no roots whatsoever. It looks nice. It works well in French."⁴ The word was already in print before her book existed: a Bridgeport, Connecticut newspaper used it twice in 1975, four years ahead of the 1979 publication.⁴

Uncertainty keeps limerence alive

Tennov's own definition turns on two conditions neither "love" nor "crush" require: uncertainty about whether the other person feels the same, and hope that they might.³ Remove either one and, in her account, the state does not sustain itself. Reciprocated, it can settle into something else entirely: ordinary love.³

Where love in her framework turns outward, limerence turns in on itself: "Limerence is self-focused; love is other-focused," in the summary Psychology Today gives of her distinction.⁵ One of Tennov's interview subjects dropped her classes altogether rather than face someone she could not stop thinking about. Tennov's research treated that kind of disruption as ordinary, not exceptional, and timed it: six months to three years, when the feeling went unanswered.⁶

Limerence is also distinct from attachment. Attachment anxiety, in the Attachment Project's account, colors a person's stance toward people in general. Limerence fixes on one specific person alone.⁷

Merriam-Webster split her single state into two

Merriam-Webster's current entry carries two senses of limerence, not one. The first, dated to 1977, is the euphoric feeling of first falling in love: a "blissful...infatuation experienced during the early period of a romantic relationship."¹ The second carries no first-known-use date of its own: "intense often involuntary romantic attachment to a person who does not reciprocate the feelings," marked by "excessive preoccupation and obsessive behaviors."¹ Neither sense is quite Tennov's. The first keeps the euphoria and drops the edge, assuming a relationship already exists, mutual and warming, not the one-sided longing of someone convinced her feelings would never be known. The second keeps the ache but assumes the rejection has already landed and settled, where Tennov's own state runs on the opposite: not yet knowing.¹ The Marginalian's account of her research calls that pull a "hope-uncertainty paradox," the fear of rejection that "may cause pain, but it also enhances desire."³ The dictionary kept both the euphoria and the obsession Tennov named. It split them into two entries rather than hold them, uncertain and hopeful at once, the way she did.
