The meaning of "limerence" falls somewhere between "infatuation"
and "romantic love". It was coined circa 1977 by Dorothy Tennov,
then professor of psychology at the University of Bridgeport,
Connecticut. It was an arbitrary coinage; there is no specific
etymology. For further information on limerence see her book
Love and Limerence (Stein and Day, 1979); or you may e-mail her

[Dorothy Tennov has sent this correction:
'The intended meaning of "limerence" is not "somewhere between
infatuation and romantic love." It was invented for a distinct state
that might look like "somewhere between" to the casual observer or poet,
but it is neither. It has distinct features not found in other states to
which the word "love" is applied. The word was created deliberately to
avoid association with "love." Then why does "love" appear in the title
of the book you may ask? It was bending to the publisher and it was a
'I would name it "Limerence: A distinct state for which a new term was
required." That's a bit long, but more accurate.'
