Phrases and clauses | Syntax | Khan Academy

Summary

This educational script explores the distinction between phrases and clauses in English grammar. A phrase, like 'my best friend' or 'for 20 days,' is a group of words functioning as a single part of speech but lacking both a subject and verb, hence not forming a complete sentence. In contrast, a clause contains a subject and a verb, such as 'the wizard cast a spell,' which can be independent (a full sentence) or dependent (requiring another clause). Examples like 'the falcon soared majestically' and 'while my guitar gently weeps' illustrate clauses, with the former being independent and the latter dependent. The script promises to delve deeper into the nuances of dependent and independent clauses in a future session.
