How Do You Use Adjectives That Start With K in a Sentence?

You use a K adjective by placing it before the noun it describes (a kind student) or after a linking verb such as is, seems or looks (the student is kind). Either way, the adjective adds one specific detail that makes the noun clearer, as the example sentences below show.

Why Is the K Silent in Some K Adjectives?

The K is silent in adjectives that begin with kn, such as knowledgeable, knotty, knitted and knobbly, because English stopped pronouncing that K hundreds of years ago while keeping the old spelling. So knotty sounds like notty, and you still write a knowledgeable guide with an a, since the word starts with an N sound.

Should an Adjective Start With K or C?

Not all adjectives beginning with a K sound are spelled with K, and not all adjectives that start with a K sound use the same letter, so an adjective that sounds like it starts with K may be spelled with K or C, so kind and keen use K, while calm and cosy use C, even though both letters make the same sound. When in doubt, check a dictionary, and see our list of adjectives that start with C for the hard-C words.

How Can You Use K Adjectives Well in Writing?

You use K 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 K adjective is the one that tells the reader precisely what you mean, not the one that sounds most impressive. He is a nice boy says very little, while he is a kind-hearted boy names the quality that makes him nice, 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 K words are nouns or verbs, so starting with K does not make a word an adjective. Kindness and knowledge are nouns, while kind and knowledgeable 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. She was a kind, kindly, kind-hearted and keen girl says less than she was a kind-hearted, keen girl, because fewer, sharper words leave a stronger picture.

Where Can You Find Adjectives That Start With Other Letters?

You can find adjectives for every other letter of the alphabet in the letter-by-letter guides below, each built the same way with positive words, words to describe someone, negative words and a full list.
