Questions about once

What is another word for once?

What is the opposite of once?

WordNet records no antonym for once. Antonymy in WordNet is a relation between specific word forms rather than between concepts, so it is recorded only where lexicographers judged the pairing direct. An absence here means none was recorded, not that none can be imagined.

Why are the synonyms for once split into groups?

Because once carries 3 recorded senses and each has its own set of substitutes. A single flat list would put words from unrelated meanings side by side with nothing to tell them apart, which is exactly how a writer picks the wrong one. The grouping comes from WordNet's synsets, not from an editorial judgement of ours.

Does this page cover every sense of once?

It covers the 2 senses that carry a synonym, antonym, broader or narrower term. The remaining 1 sense has none recorded, so it is left off a thesaurus page and shown in full on the word page instead.

Where do the synonyms for once come from?

From Princeton University's WordNet, a lexical database maintained by lexicographers since 1985. A synonym here means a word form that shares a synset with this word — a set of forms interchangeable in one recorded context. Nothing on this page is generated by a language model.
