Monosyllable
In linguistics, a monosyllable is a word or utterance of only one syllable. It is most commonly studied in the fields of phonology and morphology and it has no semantic content. It has originated from the Greek language.
"Yes", "no", "jump", "buy", and "heat" are monosyllables. The longest monosyllabic words in the English language, all containing nine letters each, are "screeched," "schlepped," "scratched," "scrounged," "scrunched," "stretched," "straights," and "strengths."
