Common CELPIP errors - Word Forms

When I was studying for my CELPIP exam I got material from them. Unfortunately, I can not put the PDF to the public because it has a watermark with my personal email. But I can put you here what it says.

CELPIP's first error as they state:

A common CELPIP error is using the wrong grammatical form of a word—that is, mixing up nouns, verbs, adjectives, and adverbs. An example is using a noun form (such as beauty) when you need the adjective form (beautiful). (Canada is a beauty beautiful country.) As shown below, a word’s required grammatical form depends on its function in a sentence.

Definitions

Adjetive

modifies nouns or pronouns

Noun

person, place, thing or idea. It serves as subject or object

Adverb

modifies verb, adjectives, or other verbs

Verb

action or state of being
