Editing Dependent clause (section)

==Adverbial clause==
{{main|Adverbial clause}}
"He saw Mary ''when he was in New York''" and "They studied hard ''because they had a test''" both contain adverbial clauses (in italics). Adverbial clauses express ''when, why, where, opposition'', and ''conditions'', and, as with all dependent clauses, they cannot stand alone. For example, ''When he was in New York'' is not a complete sentence; it needs to be completed by an independent clause, as in:

*He went to the Guggenheim Museum ''when he was in New York.''

or equivalently

*''When he was in New York'', he went to the Guggenheim Museum.
