differentiate

/ˌdɪfəˈrenʃieɪt//ˌdɪfəˈrenʃieɪt/·verb
to recognize or express what makes two or more things different
Fig. 1 — Under the microscope a row of round cells sits side by side, every one the exact twin of the next — nothing yet to tell them apart.
01Definition

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.

06TOEFL & 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.

07Asked
What does differentiate mean in calculus?
To find a derivative — the rate at which one quantity changes as another does, the slope of a curve at each point. To 'differentiate a function' is to compute that rate; the reverse operation is to integrate. The word is doing a very precise version of its everyday job: pinning down exactly how one thing changes with respect to another.
What does 'cell differentiation' mean in biology?
The process by which an unspecialised cell becomes a specific type — a nerve cell, a muscle cell, a blood cell. The scene above stages it exactly: a row of identical round cells, each committing to its own form until no two are alike. The difference was not there to be found; the cells grew it.
Is it 'differentiate between' or 'differentiate from'?
Both, with different grammar. Differentiate BETWEEN two things ('differentiate between the two theories'), or differentiate one thing FROM another ('differentiate the copy from the original'). A brand differentiates ITSELF from rivals. Between takes a pair as equals; from singles one out against a background.
What does it mean to differentiate a product or yourself?
To make plain how it is not the same as the competition — the marketing sense of standing out. 'A differentiator' is the feature that sets you apart. It keeps the word's core of drawing a visible distinction, only now the distinction is a selling point: be recognisably unlike the alternatives, on purpose.
What is the difference between differentiate and differ?
Differ is passive — to simply be unlike ('the two accounts differ'). Differentiate is active — to do the work of telling things apart or making them distinct ('the exam differentiates strong candidates from weak ones'). Things differ on their own; someone differentiates them. One is a state, the other a task.
What is the noun form of differentiate?
Differentiation — and it carries every sense the verb does: cell differentiation in biology, differentiation in calculus, product differentiation in business. One noun, three technical lives, all built on the same idea of marking or developing a difference. The adjective is differentiated ('a highly differentiated market').
What is the difference between differentiate and distinguish?
The compressed tell: you can distinguish things just by perceiving the difference, but differentiate leans toward actively making or marking it. The full contrast, with both animated scenes, is on the differentiate vs distinguish page in the 'Compared' list above.
