【Dislike】 , 【distaste】 , 【aversion】 , 【disfavor】 mean the state of mind of one who is not drawn to or turns from or avoids a person or thing; often these terms imply the manifestation of the state of mind.
【Dislike】 normally suggests the finding of something unpleasant or repugnant or of a kind one is unwilling to meet or to face. In itself 【dislike】 is rather neutral but it is readily intensified by context to the point of suggesting complete detestation.
【Distaste】 , which implies a lack of taste for, usually stresses a squeamishness or a repugnance but allows a good deal of range in intensity to this squeamishness or repugnance; it may imply such other feelings as fear occasioned by the difficulties involved or rebellion at constraint or confinement.
Austiny or simply an unexplained reluctance.
【Aversion】 suggests a disinclination for someone or something which manifests itself especially in attempts to avoid, evade, or escape.
An 【aversion】 may be temperamental or it may be the result of training; it may or may not suggest an accompanying feeling, but it consistently implies a definite reaction on the part of one manifesting it.
【Disfavor】 , the weakest of these words, usually suggests no more than a lack of liking or approval but it may imply contempt, lack of confidence, or disdain as motives.
