Confusing Words

indicates vs signifies / implies

These three verbs all describe ways in which evidence, language, or actions point to a particular meaning or conclusion, but they differ in the explicitness and certainty of the connection they signal.

  • indicates — Indicates means to point to or show something as likely or true, based on evidence or observation. It is more definite than implies and is often used in empirical and scientific writing when evidence consistently points in a direction.
  • signifies — Signifies means to be a sign or symbol of something, often carrying a particular meaning within a cultural or semiotic context. It is used when the connection between a sign and its meaning is established, not just inferred.
  • implies — Implies means to suggest something without stating it directly, leaving the reader to draw the inference. It describes a relationship that is not explicit but follows logically or contextually from what has been said.
  • suggests / denotes — suggests' points toward an idea without stating it as certain, while 'denotes' directly means or refers to something. Choose the word that matches the exact job you need it to do in the sentence.

Memory rule: A practical guide: use indicates when evidence points clearly to a conclusion; use signifies when something serves as a sign or symbol of a meaning within an established system; use implies when something is suggested but not stated, requiring the reader to infer the connection.
