Grammatical Overview

Or is a foundational coordinating conjunction in English, primarily functioning to present choices, alternatives, and possibilities. Structurally, it connects grammatically equal elements, whether they are single words (tea or coffee) or entire independent clauses (We can go out, or we can stay home). It frequently pairs with correlative markers like "either" to emphasize an exclusive choice (* either today or tomorrow*) and with "whether" to introduce alternative conditional possibilities (* whether you like it or not*). Furthermore, or can function conditionally after an imperative verb to express a warning or consequence (Stop, or I will call the police). Beyond its structural mechanics, or drives highly common discourse markers that estimate quantities (a week or so) or introduce surprising facts (believe it or not).
