c.1780, unknown author, “The Twelve Days of Christmas”, in Mirth Without Mischief:
The first day of Christmas My true love sent to me A partridge in a pear tree.
(by later reinterpretation) Love that is in some sense purer or more unique than ordinary love.
(uncountable) The form of romantic affection that is considered pure and wholly positive, not just based on feelings of lust and sex.
Some believe that true love doesn’t exist.
1847, Friedrich von Schlegel, translated by A. J. W. Morrison, The Philosophy of Life, and Philosophy of Language: In a Course of Lectures, page 38:
And as all true love is reciprocal, so also is true love lasting and indestructible; or, to “speak as a man,” even because it is the very inmost life of humanity, it is, therefore, true unto death.
