“discreet” vs. “discrete”
Use "discreet" for careful, tactful, low-key behavior, and "discrete" for things that are separate or individually distinct.
discreet
"Discreet" is an adjective meaning careful, tactful, or deliberately unobtrusive, especially about sensitive matters ("she made a discreet exit," "he was discreet about the negotiations"). It comes from Latin "discretus" (separated, discerned), by way of Old French, originally carrying the sense of having good judgment or discernment before narrowing to today's meaning of careful, tactful restraint.
discrete
"Discrete" is an adjective meaning separate, distinct, or individually distinguishable ("the project has three discrete phases"). It comes from the exact same Latin root, "discretus," but took a more direct, unshifted path into English, keeping the original sense of "separated" or "distinguished from others" almost unchanged across the centuries, unlike "discreet," whose meaning drifted toward tact and restraint.
The real distinction
"Discreet" and "discrete" are true etymological twins — literally the same Latin word, "discretus," that split into two English spellings carrying two different modern meanings, one about careful behavior and one about separateness. The double e in "discreet" is a useful anchor: two e's sitting together, like two people keeping a secret between themselves, discreetly. "Discrete," by contrast, keeps its letters cleanly separated by the intervening consonant, a small visual echo of its own meaning: distinct, individually separated units. Mathematics, computer science, and statistics rely heavily on "discrete" in a precise technical sense — a "discrete variable" takes on distinct, separate values (like whole numbers) rather than a continuous range, and this technical usage is one of the more common places general readers first encounter the less-familiar spelling. Because "discreet" is the far more frequent word in everyday writing (deriving from its everyday social meaning of tact and low-key behavior), while "discrete" appears mostly in technical, academic, or precise analytical writing, many writers default to the more familiar "discreet" spelling even in sentences that actually call for "discrete," an error that shows up often in business writing describing separate categories, phases, or components. Editors reviewing academic and technical manuscripts specifically watch for this swap, since a paper meaning to describe "discrete data points" that instead reads "discreet data points" changes the sentence from a statement about statistical structure into unintentional nonsense about data behaving tactfully. Because spell-checkers accept both spellings as valid words, this pair joins the small group of homophone-like errors that survive automated proofreading entirely, meaning a dedicated human read-through, or a grammar-aware tool checking actual word usage in context, is the only reliable safeguard, especially in any document mixing casual and technical language, where both meanings might plausibly show up close together, such as a business report describing both confidential negotiations and separate financial categories in the same paragraph.

Memory trick
Picture the two e's in "discreet" as two people standing quietly side by side keeping the same secret, while the t sitting between the two halves of "discrete" visually separates them, echoing the word's own meaning of separateness. One more useful check: if you could substitute "tactful" or "low-key," you need "discreet"; if you could substitute "separate" or "distinct," you need "discrete."
