Sense: preposition/1
Unlike, different from, distinct from, and in contrast to all indicate that two things are not the same, but they differ in typical contexts. Unlike is the most concise and conversational: it sits naturally at the start of a sentence ('Unlike her sister…'). Different from is the most neutral and widely accepted in both speech and writing, though some speakers use 'different than' in American English. Distinct from emphasises clear separation — two things are not merely different but belong to separate categories. In contrast to is the most formal and signals a deliberate, often rhetorical comparison, common in academic essays and speeches. For everyday contrast, unlike is the smoothest choice; for precise classification, use distinct from; for formal written comparisons, choose in contrast to.

Etymology
Unlike comes from Old English ungelīc, a compound of the prefix un- (meaning 'not') and gelīc (meaning 'like, similar'). The prefix un- has Germanic origins and is one of the most productive negating prefixes in English. The root gelīc descends from Proto-Germanic *galīkaz ('having the same form') and is related to Old Norse líkr, Dutch gelijk, and German gleich. The modern social-media verb sense (meaning 'to remove a like') is a much more recent coinage from the early 2000s, formed by adding un- to the noun/verb like as used on platforms such as Facebook.
