To dislike or regard with disfavor; to feel aversion toward something.
From dis- (negation) + alike (similar, agreeable). This is an archaic or obsolete form that adds the negation prefix to 'alike' to express strong dislike.
This is basically an old-fashioned way of saying 'dislike,' but it's interesting because English has so many ways to express negative feelings—we could use dislike, hate, detest, or abhor, each with slightly different intensities.
