Usage

What are other ways to say meaningful? When describing forms of expression, the adjectives meaningful and significant imply an underlying and unexpressed thought whose existence is plainly shown although its precise nature is left to conjecture. Meaningful implies a secret and intimate understanding between the persons involved: Meaningful looks passed between them. Significant suggests conveying important or hidden meaning: On hearing this statement, he gave the officers a significant glance. 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.
