Definition
To differentiate is to tell apart — to find and mark the features that separate one thing from another it resembles. A scientist differentiates two species by a single bone; a brand differentiates itself from its rivals; a teacher helps students differentiate near-synonyms. The word is about drawing distinctions that were not obvious before, and it can be reflexive: to differentiate yourself is to make plain how you are not the same as everyone around you.
Examples
- Skilled tasters can differentiate two coffees that seem identical, trained to discern a difference most people miss.
- The exam tests whether you can differentiate cause from correlation — a subtle distinction that trips up many candidates.
- Firms work hard to differentiate their products in a crowded market.

In TOEFL & IELTS
Common in TOEFL academic lectures ('differentiate between the two theories') and in IELTS prompts that ask you to compare. Use 'differentiate between A and B' or 'differentiate A from B'. It is a clear step up from 'tell the difference' and signals analytical writing. Don't confuse it with 'differ' (to be unlike): to differentiate is the active work of marking how things differ.
