Synonym Discussion of NASTY

dirty, filthy, foul, nasty, squalid mean conspicuously unclean or impure. dirty emphasizes the presence of dirt more than an emotional reaction to it <a dirty littered street>. filthy carries a strong suggestion of offensiveness and typically of gradually accumulated dirt that begrimes and besmears <a stained greasy floor, utterly filthy>. foul implies extreme offensiveness and an accumulation of what is rotten or stinking <a foul-smelling open sewer>. nasty applies to what is actually foul or is repugnant to one expecting freshness, cleanliness, or sweetness <it's a nasty job to clean up after a sick cat>. In practice, nasty is often weakened to the point of being no more than a synonym of unpleasant or disagreeable <had a nasty fall> <his answer gave her a nasty shock>. squalid adds to the idea of dirtiness and filth that of slovenly neglect <squalid slums>. All these terms are also applicable to moral uncleanness or baseness or obscenity. dirty then stresses meanness or despicableness <don't ask me to do your dirty work>, while filthy and foul describe disgusting obscenity or loathsome behavior <filthy street language> <a foul story of lust and greed>, and nasty implies a peculiarly offensive unpleasantness <a stand-up comedian known for nasty humor>. Distinctively, squalid implies sordidness as well as baseness and dirtiness <engaged in a series of squalid affairs>.
