My Flashcards

Definition

Meaning

A particular order in which related events, movements, or things follow each other.

A set of related events, actions, items, or DNA nucleotides following a logical or chronological order; in film, a distinct episode or section.

Linguistics

Semantic Notes

Primary sense is about ordered succession; can imply causality or just chronology. In mathematics/film/computing, it's a highly technical term.

Dialectal Variation

British vs American Usage

Differences

No significant lexical differences. Spelling identical. In academic contexts, 'sequencing' as a gerund is equally common.

Connotations

Identical. Both associate it with order, logic, and technical processes.

Frequency

Slightly more frequent in American academic and tech writing due to larger STEM output, but difference is marginal.

Think of SEE-quence – you need to SEE the order to understand the sequence.

Conceptual Metaphor

TIME IS A LINE OF EVENTS (events are points on a line in sequence).

Watch out

Common Pitfalls

Translation Traps (for Russian speakers)

  • Avoid translating as 'сиквенс' (false friend, rarely used). Use 'последовательность' (order) or 'серия' (series) depending on context. Don't confuse with 'consequence' (последствие).

Common Mistakes

  • Confusing 'sequence' with 'series' (series doesn't stress order as strongly). Misspelling as 'sequance'. Using 'sequence of' incorrectly with uncountable nouns.

FAQ

Frequently Asked Questions

No, while often chronological, it can refer to any defined order (logical, spatial, numerical, or algorithmic).

'Series' suggests items in succession but may not imply a strict, logical, or necessary order. 'Sequence' strongly implies a deliberate or inherent order connecting the items.

Yes, especially in scientific contexts (to sequence DNA) or general use (to sequence tasks).

Very similar. 'In sequence' stresses following the defined order, while 'consecutively' stresses following one after another without interruption.
