Implied reference is a way of hinting at something without directly stating it. Synonyms for this term include indirect allusion, insinuation, suggestion, implication, and inferred mention. These synonyms all refer to the subtle way in which information is hinted at or suggested, rather than explicitly stated. Using implied references can be an effective communication tactic, as it allows the speaker or writer to convey complex ideas in a more subtle and nuanced way. It also encourages the listener or reader to think critically and draw their own conclusions based on what is suggested, rather than simply accepting what is explicitly stated.
