and most other language
s (including Japanese
), independent clause
s are linked together by conjunction
s, such as "and", "or", "but", etc. Subordinate clause
s (the other type) cannot stand on their own and are linked with words like "because" or "so".
Independent clauses can be separated and still retain the same meaning. Subordinate clauses become fragments when separated from their subordinating clauses. A common grammatical error in English.
