What does subclause mean?
A subclause is a smaller grammatical unit that functions within a larger clause. It contains a subject and a predicate, but it cannot express a complete thought on its own and instead depends on the surrounding main clause for some part of its meaning. For example, in “The team celebrated after the final whistle,” the phrase “after the final whistle” is a subclause. The term is particularly useful in grammatical analysis because it distinguishes a dependent unit from the independent or main clause that completes the sentence. In legal and formal contexts, a subclause may also mean a secondary division of a larger contract, statement, or provision, though the grammatical sense is the most established. “Subordinate clause” and “dependent clause” are the most common alternatives, while “subclause” provides a concise and formally precise label.
nounA clause that forms part of a larger clause and does not by itself express a complete thought. It is also commonly called a subordinate or dependent clause.
- A grammatical clause that is grammatically dependent on another clause and cannot constitute a complete sentence by itself.
"The committee approved the proposal after the members had completed their review."
"Because the evidence was incomplete, the researchers delayed their conclusion."
"The final clause of the agreement may be modified by a separate written addendum."
The usual plural in grammatical analysis and formal prose.
"The exercise asks students to identify the main clauses and subclauses in each sentence."
A subclause is a clause that cannot stand alone: it leans on the main clause to complete its meaning.

Where does subclause come from?
The word is formed in English by combining the prefix “sub-,” meaning under or subordinate, with “clause.” “Clause” comes through French from Latin “clausula,” a diminutive of “clausus,” meaning closed, referring to a grammatical unit that encloses or completes a thought. The combination “subclause” developed as a grammatical term in the modern English period.
