Restrictive and nonrestrictive adjective clauses
| Question | Answer |
|---|---|
| Restrictive adjective clause | It significantly affects the meaning of the noun it modifies by limit or narrowing the meaning of that noun. If you delete it, it completely changes the meaning of the original sentence |
| Nonrestrictive adjective clauses | They give additional information about the nouns they modify, but this information does not affect or alter the basic meaning of that noun. Typically, they give supplementary information. The deletion does not change the basic meaning of the noun. |
| If a clause is nonrestrictive does that mean the information is unimportant? | NO, sometimes it is very important |
| Key distinction between restrictive and nonrestrictive adjective clauses | The effect of the information on the modified nouns |
| What is the distinction between res and nonres in speaking? RES | In res, the clause is pronounced in the same phrase unit as the noun. It is said with an upwards intonation that drops abruptly at the end of the clause. There is a distinct pause after the clause. |
