WORD ARCHIVE
BOO
BOO is an expression of disappointment, or a sound used to frighten
What BOO does
BOO serves two almost opposite functions: the BOO of disapproval (audience booing a performer) and the BOO of fright (jumping out to scare someone). Same word, opposite intentions.
BOO as literary candidate
BOO's dual meaning is a small linguistic puzzle. Disapproval-BOO and fright-BOO share a phonetic form but different emotional vectors. The Archive is interested in this kind of word: one that does too much for its size.
