Sequentially

Sequentially is an adverb describing the manner in which events, operations, or processes occur in a sequence, one after another, following a defined order. It denotes temporal ordering, as when events unfold in time, or logical ordering, as when tasks must be completed in a prescribed progression. The term emphasizes dependency on prior steps and an absence of overlap between activities described as sequential.

In everyday language it is used to specify order in instructions and procedures. In computing and data processing, sequential execution or access processes data step by step in a linear fashion, contrasting with parallel or concurrent methods. In experimental design or workflow planning, performing tasks sequentially helps control variables and ensure reproducibility. The adverb can also appear in mathematical or logical contexts, where a sequence is evaluated or validated in order.

Origin and related forms: sequential derives from the Latin sequi, to follow, via the adjective sequential and the adverbial suffix -ly. Related terms include sequence, sequential, serial, consecutive, and sequential logic, which describe related notions of ordering and progression.
