either ... or

Muster: either · SLOT · or · SLOT

A correlative conjunction pattern used to connect two parallel elements (words, phrases, or clauses) and present a strict choice between them. It emphasizes that only one of the options can be true, chosen, or happen. The structure requires grammatical parallelism, meaning both parts after 'either' and 'or' should have the same grammatical form. It is commonly used in both spoken and written English to express alternatives, decisions, or mutually exclusive conditions.
