What is an adjective?

In general, an adjective describes or modifies a noun or pronoun.

The letter J did not appear in English until the Middle Ages. Originally, it was the letter I, and it was the last letter added to the alphabet. It was initially used to represent the last letter in Roman numerals; the number 12 may appear as “xij” for example. Although J is not one of the most prevalent consonants in English, many adjectives in the language start with it. In a sentence, an adjective may appear before a noun or pronoun, after a noun or pronoun, or modify a word that is not in the sentence. By using adjectives that start with J your writing should become jaw-dropping and jazzy instead of judgmental and jumbled. In this guide, you will learn the definitions of several J adjectives and examples of how to use them. This guide will cover 20 adjectives in total.
