1. Connecting two elements to indicate joint inclusionA2formal

   Used to link two grammatically parallel elements (nouns, adjectives, verbs, phrases, or clauses) to show that both are true, present, or applicable at the same time. The structure requires strict parallelism: if 'both' precedes a noun, 'and' must also connect a noun; if it precedes a verb phrase, the second element must match. The verb following a compound subject with 'both...and' is always plural.
