disambiguate

verb

1. To remove ambiguities from; to make less ambiguous; to clarify or specify which of multiple possibilities applies – e.g., possible meanings of an ambiguous statement – or to invite or require this.
2. To distinguish one word or lexical unit (from a different one which has a similar form).

   “When necessary, the Greek spelling is disambiguated by an appended phonetic transcription.”

   “The dictionary's traditional “readers” have largely survived this transition, too. They find earlier and better uses of terms which computers can't (in the jargon) disambiguate—distinguish from other similar uses.”
