How Can You Use I Adjectives Well in Writing?

You use I adjectives well by choosing the one word that names the exact quality you mean, checking that it really is an adjective and avoiding long strings of describing words. These three habits keep writing clear, specific and easy to read.

Choose the Exact Word

The best I adjective is the one that tells the reader precisely what you mean, not the one that sounds most impressive. He is a good student says very little, while he is an inquisitive student names the quality that makes him stand out, and swapping vague words for exact ones is one of the easiest ways to improve a child's writing skills.

Check It Is Really an Adjective

Many I words are nouns or verbs, so starting with I does not make a word an adjective. Imagination and intelligence are nouns, while imaginative and intelligent are the matching adjectives, so always check that the word is describing a noun in your sentence.

Avoid Piling Up Adjectives

Adding more adjectives does not automatically make writing better, and a long string of them often weakens a sentence. It was an incredible, impressive, interesting, inspiring and ingenious project says less than it was an ingenious, inspiring project, because fewer, sharper words leave a stronger picture.
