Discreet means careful, tactful, and good at keeping things private (a discreet inquiry, discreet packaging); its noun is discretion. Discrete means separate, distinct, and individually unconnected (three discrete categories, discrete data); its noun is discreteness. They sound identical, so the difference is purely about meaning and spelling.
Discreet and discrete are homophones: they share the pronunciation /dɪˈskriːt/ but have completely unrelated meanings. Both are adjectives, both come from the same Latin root discretus (“separated”), and they differ only in the position of one letter. That tiny spelling difference carries the entire distinction in meaning, which makes this one of the most commonly confused pairs in written English at C1 level.

Using “Discrete”
Discrete describes things that are separate, distinct, and individually identifiable. If something is made up of parts that do not blend into one another — that stand apart as separate units — those parts are discrete. The word is especially common in mathematics, science, and statistics.
Definition
Individually separate and distinct; consisting of distinct or unconnected parts. In maths and statistics, discrete describes data that can take only specific, separate values (the opposite of continuous). The related noun is discreteness, and the adverb is discretely.
When to use it
- Describing separate, distinct parts or categories: three discrete stages
- In mathematics and computing: discrete mathematics, discrete values
- In statistics: discrete data (countable, e.g. number of children) versus continuous data
- In science and engineering: discrete components, discrete particles
- When emphasising that items are unconnected and do not overlap

The Key Difference
The single most important point is that these words have nothing to do with each other in meaning, despite sounding identical. Discreet is about behaviour — being tactful, private, and unobtrusive. Discrete is about structure — being separate and individually distinct. If you are talking about a person being careful and tactful, you want the double-e spelling, discreet. If you are talking about things being separate, you want discrete.
About behaviour (tactful, private):
He was discreet about his colleague's illness.
About structure (separate, distinct):
The illness progresses through several discrete phases.
Because discreet is by far the more common word in everyday writing, many people reach for it by habit even when they mean discrete. In technical, scientific, or mathematical writing, discrete is almost always the one you need.

Look at the two e's in each word. In discrEtE the two e's are separated by the t (E–T–E) — just like the separate, distinct things that discrete describes. In discreEt the two e's sit together, hidden close like a secret — just like a discreet person keeps things close and private. Separated e's = separate things (discrete); e's kept together = keeping a secret (discreet).
