What does discretely mean?
"Discretely" is an adverb meaning in a separate or distinct manner — as individual, self-contained units rather than as part of a continuous whole. It derives from the adjective "discrete," which itself traces back to the Latin discretus, meaning separated or distinguished, the past participle of discernere, "to distinguish." In practice the word belongs chiefly to technical registers: mathematicians speak of values varying discretely rather than continuously, computer scientists describe signals sampled discretely at intervals, and engineers treat components as operating discretely instead of as an integrated system. Its defining contrast is with continuity — where something continuous flows without gaps, something discrete comes in countable, bounded pieces. The word carries no emotional connotation; it is precise and neutral. Its chief pitfall is its perfect homophone "discreetly," which means tactfully or cautiously, and even experienced writers occasionally swap the two, making this pair one of English's classic spelling traps.

"Each question is scored discretely, allowing the results to be analysed item by item."
One tiny 'e' splits two words that sound identical but mean opposite things: doing something discretely keeps it apart; doing it discreetly keeps it quiet.

Etymology of discretely
"Discretely" comes from "discrete," borrowed into English in late Middle English from the Latin discretus, the past participle of discernere, meaning to separate or distinguish. The Latin root also produced "discretion" and, through related development, words like "discern" and "discriminate," all built on the idea of telling things apart. For centuries "discrete" and "discreet" were variant spellings of the same word, both covering the senses of being separate and being prudent; only in recent centuries did their meanings split cleanly, leaving "discretely" with the sense of separateness.

How discretely is actually used
Primarily a formal or technical term, most at home in mathematics, statistics, computing, engineering, and scientific writing, where it contrasts with 'continuously'. In everyday prose it is rare and may strike readers as odd unless the contrast between separateness and wholeness is genuinely intended.
Easily confused with discretely
"Discretely" means separately or as distinct units, while "discreetly" means carefully and tactfully so as to avoid drawing attention.
