Vocable
In the broadest sense of the word, a vocable (from Latin: vocabulum) is any identifiable utterance or writing, such as a word or term, that is fixed by its language and culture. The use of the term for words in the broad sense is archaic and the term is instead used for utterances which are not considered words, such as the English interjections of assent and denial, uh-huh and uh-uh , or the interjection of error, uh-oh .
