synonym search

You can search for synonyms of a word using the equals sign, e.g. “=nice” gives you (in COCA) good, kind, particular, fine, etc. You can then click on the [S] behind the synonyms to look for the synonyms of that particular word.

Combinations of lemma and PoS searches with synonym searches are permissible, e.g. “=CLEAN_v” if you’re interested in only the verb synonyms.

You can find complete overviews of the search syntax in the BYU interface, the Lancaster BNC interface, AntConc and regular expressions in AntConc here.
