The Only Use of

conceit

in

A Midsummer Night's Dream

Thou, thou, Lysander, thou hast given her rhymes, And interchang'd love-tokens with my child: Thou hast by moonlight at her window sung, With feigning voice, verses of feigning love; And stol'n the impression of her fantasy With bracelets of thy hair, rings, gawds, conceits, Knacks, trifles, nosegays, sweetmeats,—messengers Of strong prevailment in unharden'd youth;— With cunning hast thou filch'd my daughter's heart; Turned her obedience, which is due to me, To stubborn harshness.†
Scene 1.1
