main clause

Definition of main clause

noun

Grammar
  • a clause that can form a complete sentence standing alone, having a subject and a predicate. Contrasted with subordinate clause.

Grammar

Every full sentence contains at least one main clause. Sometimes two (or more) main clauses are linked together using coordinating conjunctions to form a compound sentence:

main clause coordinating conjunction main clause
Aja knew everyone in town.
My father-in-law had a great gift for friendship.
No man can face this situation without uneasinessandthese circumstances were exceptional.
The two clauses in the last example can be joined in other ways, by making one of them dependent on the other: by turning it into a subordinate clause:
main clause subordinating conjunction subordinate clause
No man can face this situation without uneasinesssothese circumstances were exceptional.
subordinating conjunction subordinate clause main clause
Althoughno man can face this situation without uneasinessthese circumstances were exceptional.
