Tell it apart
| Aspect | Discreet | Discrete |
|---|---|---|
| Means | Tactful; careful to keep things private | Separate; distinct from the others |
| Describes | People and their actions | Parts, units, categories, data |
| Example | 'She made a discreet exit.' | 'The course has five discrete modules.' |
| Noun form | Discretion | Discreteness |
Discreet is about behaviour: tactful, careful, quietly private. Discrete is about structure: separate, distinct, countable. They're pronounced the same and share a Latin root, discretus, 'separate', but they reached English by different routes and now never overlap.
What it really means
Discreet and discrete are homophones with a hidden family tie. Say them aloud and you can't tell them apart; write them down and one swap of e and t changes the meaning entirely.
Discreet describes people and how they behave. A discreet friend keeps your secret; a discreet glance at the clock doesn't interrupt the meeting; a discreet enquiry gets information without drawing attention. Its noun is discretion, as in "use your discretion" or "the soul of discretion".
Discrete describes how things are divided. Discrete parts are separate from one another, with clear edges between them: discrete stages of a project, discrete categories in a survey. In mathematics it has a specific job, describing values that come in separate, countable steps rather than a smooth continuum. Its noun is the plainer discreteness.
The two are siblings. Both descend from Latin discretus, "separate". The version that came through French picked up the sense of being discerning, and from there prudent and tactful, giving us discreet. The version borrowed straight from Latin stayed literal, giving us discrete. Both entered English in the 1300s, according to Dictionary.com.
Memory trick. In discrete, the t sits between the two e's and keeps them apart: separate, like the word means. In discreet, the two e's stay close together, keeping each other's secrets.
In real life
- Right: He was discreet about his plans to leave. (tactful, private)
- Right: The survey sorts answers into discrete categories. (separate)
- Wrong: Please be discrete when you mention it to her. (tact is 'discreet')
Questions
Q01What is the difference between discreet and discrete?
Discreet means tactful or careful to keep something private ('a discreet word in her ear'). Discrete means separate or distinct ('discrete stages'). They sound identical, so only the spelling tells them apart.
Q02What does discrete mean in maths?
In mathematics and science, discrete describes things that come in separate, countable values rather than a continuous range, like the number of people in a room as opposed to their heights.
Q03Are discreet and discrete related?
Yes. Both go back to Latin discretus, 'separate'. Discreet came through French with the sense 'discerning', which became 'prudent'; discrete was borrowed straight from Latin and kept the 'separate' meaning.
