A double-entendre is a word or phrase that has two possible interpretations, with one often being suggestive or risque. Its antonyms, or opposite words, are those that have only one clear meaning, without any ambiguity or insinuation. Some examples of antonyms for double-entendre could be straightforward, unambiguous, literal, clear-cut, univocal, direct, or unequivocal. These words denote a sense of clarity, simplicity, and transparency, which is diametrically opposed to the subtle and suggestive nature of a double-entendre. Using these antonyms can help avoid misunderstandings or misinterpretations that may arise from using ambiguous language or innuendos.
