correlatives

Correlatives are words or phrases that occur in paired, dependent structures to connect corresponding elements in a sentence. In English, the best-known correlative conjunctions are not a single word but a pair of items, such as either... or, neither... nor, both... and, and not only... but also. Other correlative patterns include no sooner... than, the more... the more, and whether... or.

Correlative constructions require parallelism between the linked elements. The items joined by the correlative should match in part of speech and function; for example, nouns with nouns, verbs with verbs, or clauses with clauses. They can introduce contrasts, choices, gradation, or comparisons, and they often affect word order, as in the case of inversion when not only is emphasized: Not only did she arrive on time, but she also brought documents.

In usage, correlatives help to structure complex relationships and to add emphasis. They should be used to ensure balance between the linked elements and to avoid mixing incompatible forms. When the paired segments are long, sentence rhythm and clarity can suffer, so concise phrasing is preferred.

Examples: Either you start the project now or you will miss the deadline. Neither the manager nor the staff were aware of the change. Both the title and the author were listed. Not only did the plan fail, but it also wasted resources. No sooner had the ceremony begun than the power failed. The more you practice, the better you will become. Whether you accept the offer or decline it remains your decision.
