Funny Descriptive Words That Start With O

Adjectives are descriptive words that help us add an extra touch of excitement, intensity, and cohesiveness to our sentences. Our nouns and pronouns would sound rather plain and dull on their own if we don't add descriptive words for them.

Besides, readers wouldn't find anything enticing in a piece of writing and would perhaps not want to read at all. This is why we rely heavily on the use of adjectives to improve the quality, structure, and information level of our sentences.

We know grammar concepts can confuse anyone. They can be really tricky at times but it helps to have extra resources. We offer book video explanations and common core English resources to help make language concepts easier for children to understand.

Adjectives – What they are

There are many uses of adjectives, including describing how many or how much of the nouns or pronouns you're describing. They also help you discuss the kind of things you want, see, or have experienced, etc. For example:

Place two white chairs on the stage, please.

Here you can see that two and white serve as modifying adjectives in the sentences. We also have other kinds of adjectives, including possessive adjectives, demonstrative adjectives, and number adjectives. This helps indicate possessions, demonstrate things and persons, etc. and state the number of nouns and pronouns.
