unimpressed

Unimpressed is an adjective used to describe a lack of admiration, astonishment, or interest in response to something perceived as noteworthy. It conveys a sense that the subject has not been moved, impressed, or persuaded by a claim, performance, or object. The degree of unimpressedness can range from mild skepticism to outright indifference, and it is frequently expressed through tone of voice, facial expression, or concise language such as "I wasn't impressed."

Unimpressed is formed from the negative prefix un- added to the participle "impressed," which derives from Latin imprimere via Old French imprimer. In modern English, "unimpressed" is almost exclusively used attributively or predicatively. The word is an adjective; the typical construction is "unimpressed by/with X" or "to be unimpressed" (someone being unimpressed). The adverbial form "unimpressedly" is rare and generally not used; speakers usually turn to "unimpressed by" or simply "unimpressed" with an accompanying verb.

In criticism and everyday speech, "unimpressed" can signal skepticism about claims, products, performances, or intentions. It does not imply strong negative judgment on every aspect, but rather a failure to meet expected standards or excitement. It may be used humorously or sarcastically in informal contexts, whereas in formal writing one might opt for more precise terms such as "not impressed" or "not persuaded."

Related terms include indifferent, unmoved, and skeptical; antonyms include impressed, astonished, and wowed. The concept is a common communicative stance in reviews, social media commentary, and interpersonal assessments when enthusiasm fails to materialize.
