Usage

What are other ways to say significant? The adjectives significant and meaningful, when describing forms of expression, imply an underlying and unexpressed thought whose existence is plainly shown although its precise nature is left to conjecture. Significant suggests conveying important or hidden meaning: On hearing this statement, he gave the officers a significant glance. Meaningful implies a secret and intimate understanding between the persons involved: Meaningful looks passed between them. Expressive suggests conveying, or being capable of conveying, a thought, intention, emotion, etc., in an effective or vivid manner: an expressive gesture. Suggestive implies an indirect or covert conveying of a meaning, sometimes mentally stimulating, sometimes verging on impropriety or indecency: a suggestive story or remark.
