Definition
Unalike means not alike — sharing no resemblance, failing to correspond. It is built plainly from un-, 'not', and 'alike', and it usually describes two things set side by side that simply do not match: two unalike siblings, two unalike halves. Where dissimilar leans formal and technical, unalike is the plainer word, and it stresses the absence of any answering likeness — nothing in the one echoes the other. It almost always follows what it describes ('the two are unalike') rather than standing before a noun.
Examples
- However hard you look, the two accounts are utterly unalike and refuse to line up.
- Their tastes are so unalike that the two friends rarely resonate over a single film.
- The two species are unalike enough that even a novice can distinguish them.

In TOEFL & IELTS
Plainer and less common than its twin dissimilar, and almost always predicative — it follows the noun ('the two are quite unalike'), rather than sitting before it. Useful in Speaking and writing to stress that things share no resemblance at all. Built transparently from 'un-' + 'alike', so the meaning is easy; the skill is choosing it over dissimilar when you mean simple non-correspondence rather than difference in kind.
