1.verbtransitiveB2
Definition

to notice or point out what makes two or more things unlike each other when you compare them side by side

Example

Joaquín found it hard to differentiate real butter from margarine in a taste test.

differentiate between X and Y

The teacher showed the class how to differentiate male frogs from females by ear size.

differentiate X from Y

Common collocations
  • differentiate between
  • differentiate from
  • hard to differentiate
  • easy to differentiate
  • clearly differentiate
Synonyms
  • distinguish

    more common in everyday English; 'differentiate' implies a more careful or technical comparison

  • tell apart

    informal phrasal verb; used mainly with can/could (e.g. 'I cannot tell them apart')

Antonyms
  • confuse

    to mistake one thing for another

Grammar Patterns

differentiate between X and Y

differentiate X from Y

Usage Note

Often paired with 'between' (to compare two items side by side) or 'from' (to separate one from a broader category). 'Differentiate' sounds more analytical and formal than the everyday phrase 'tell apart', while 'discriminate' can carry unwanted connotations of unfair bias in social contexts.

Common Mistakes

Can you differentiate me the two paintings?
Can you differentiate between the two paintings?
'differentiate' does not take two objects; use 'between' or 'from'.
I can differentiate the difference between them.
I can differentiate between them.
'differentiate' already contains the idea of noticing a difference, so the word 'difference' is redundant.

2.verbtransitiveB2
Definition

to be the quality or feature that makes one person or thing noticeably unlike others of the same type

Example

What differentiates this laptop from cheaper models is the quality of its cooling system.

what differentiates X from Y

Anya's ability to speak four languages differentiates her from other candidates during job interviews.

X differentiates Y from Z

Common collocations
  • what differentiates
  • differentiate from competitors
  • differentiate a brand
  • differentiate a product
Synonyms
  • distinguish

    very similar; 'distinguish' is slightly broader and can be used both for 'telling apart' and 'setting apart'

  • set apart

    informal phrasal verb; often used in the same pattern ('what sets it apart')

Grammar Patterns

X differentiates Y from Z

what differentiates X is

Usage Note

Subject is usually the distinguishing feature itself (a quality, a characteristic), not a person doing the differentiating. Common in business and marketing contexts where a 'differentiator' is a feature that gives a product a competitive advantage.

Common Mistakes

This feature differentiates this car with others.
This feature differentiates this car from others.
always use 'from', not 'with', after 'differentiate'.
Hard work differentiates among successful people.
Hard work differentiates successful people from unsuccessful ones.
use 'from', not 'among', for this meaning.

3.verbintransitiveC1
Definition

to change from a simple, unspecialised cell into a more complex cell with a specific job, such as a muscle cell or a nerve cell, during the growth of a living thing

Example

During early development, stem cells differentiate into specialised cells that form the heart and brain.

cells differentiate into [cell type]

Mayumi studies why stem cells differentiate into skin cells rather than nerve cells.

differentiate into X rather than Y

Common collocations
  • cells differentiate
  • differentiate into
  • stem cells differentiate
  • differentiate during development
Synonyms
  • specialise

    broader term used for any process of becoming adapted to a specific function; not limited to cell biology

Antonyms
  • dedifferentiate

    highly technical; the return of a specialised cell to a simpler, unspecialised state

Grammar Patterns

cells differentiate into [cell type]

[cell] differentiates to form [structure]

Usage Note

Almost exclusively used in biology and medicine. Frequently occurs in the pattern 'cells differentiate into [specific cell type]'. The noun form 'differentiation' (細胞分化) is equally common in scientific writing. The opposite process is 'dedifferentiation', where a specialised cell returns to a simpler state.

Common Mistakes

The stem cell differentiates a heart cell.
The stem cell differentiates into a heart cell.
the cell itself changes into something else; use 'into', not a direct object.
Different cells differentiate different jobs.
Different cells differentiate to perform different jobs.
'differentiate' describes what the cell becomes, not what it does directly.

4. to use a mathematical process to find the rate at which a function is changing a

4.verbtransitiveC1
Definition

to use a mathematical process to find the rate at which a function is changing at a particular point, producing a new function called the derivative

Example

In calculus class, Hao learned how to differentiate the function f(x) equals x squared.

differentiate [function]

To find a curve's slope at any point, you must differentiate its equation.

Common collocations
  • differentiate a function
  • differentiate with respect to
  • differentiate an equation
Antonyms
  • integrate

    the inverse mathematical operation; integration finds the original function from its derivative

Grammar Patterns

differentiate [function]

differentiate [function] with respect to [variable]

Usage Note

Used in calculus and related fields such as physics and economics. The verb is typically transitive, taking a function expression as its object. The noun form 'differentiation' (微分) refers to the process itself, and 'derivative' (導數) is the result.

Common Mistakes

Differentiate the function 5 times.
Differentiate the function with respect to x.
'times' is not the correct mathematical term; use 'with respect to' to specify the variable.
I differentiated and got the slope.
I differentiated the function and obtained the slope formula.
'differentiate' needs an object; you differentiate a function, not just 'differentiate' alone.

5.verbtransitiveC1
Definition

to adapt the content, activities, or pace of a lesson so that students of different ability levels can all learn effectively in the same classroom

Example

Emre differentiates his maths lessons by giving fast learners harder problems and others more practice.

differentiate [subject] by offering [options]

The school asks teachers to differentiate instruction so each child learns at their own pace.

differentiate instruction

Common collocations
  • differentiate instruction
  • differentiate a lesson
  • differentiate for students
  • differentiated classroom
  • differentiate by ability

Grammar Patterns

differentiate instruction for [students]

differentiate [subject] by [method]

Usage Note

Common in educational training and pedagogical literature. The noun phrase 'differentiated instruction' (差異化教學) is a standard term in teaching methodology. This usage is distinct from sense 1 in that the teacher is not comparing things but rather adjusting methods to meet varied needs.

Common Mistakes

The teacher differentiates the students by level.
The teacher differentiates the lesson for students of different levels.
you differentiate the material or instruction, not the students themselves.

Synonym discussion

Sense: verb/1

All three words refer to noticing how things are not alike. 'Distinguish' is the broadest and most neutral term: you can distinguish a bird by its song, or distinguish yourself through hard work. 'Differentiate' overlaps with 'distinguish' in sense 1 but carries a more analytical, methodical tone — you differentiate between options by systematically comparing features. 'Tell apart' is the informal, conversational alternative: 'I cannot tell the twins apart' sounds natural, while 'I cannot differentiate the twins' sounds oddly formal. 'Discriminate' is more problematic: in technical or scientific writing it means the same as 'differentiate' (e.g., 'the test discriminates between infected and healthy subjects'), but in everyday language it usually implies unfair treatment based on prejudice. For classroom use, 'differentiate' is the safest choice for neutral, analytical comparison. For example: 'The wine expert can differentiate between two vintages that taste nearly identical to most people.'

Etymology

LatinFrenchEnglish

From Latin 'differentia' meaning 'difference' or 'distinction', formed from 'differre' (to carry apart, to differ) — itself from 'dis-' (apart) + 'ferre' (to carry, to bear). Entered English in the 16th century with the general meaning 'to make or recognize a difference'. The mathematical sense appeared in the late 17th century alongside the development of calculus by Newton and Leibniz. The biological sense, referring to cell specialisation, emerged in the 19th century with advances in microscopy and embryology. The educational sense is the most recent, dating from the late 20th century as theories of differentiated instruction developed.
