Final answer:
An adjective modifies or describes nouns. It can have characteristic endings and can be modified using qualifiers and comparative words.
Step-by-step explanation:
An adjective is a word that modifies or describes nouns. It can have characteristic endings such as -ous (delicious), -ish (waspish), -ful (beautiful), and -ary (wary). Adjectives can be modified using qualifiers like very, extremely, and comparative words like more, most, less, and least. Just like with nouns, adjectives and their modifiers can form adjective phrases.
For example, in the sentence 'I need to find an affordable car', the adjective 'affordable' is modifying the noun 'car'. In the sentence 'Ms. Chu needs to find a more reliable car', the adjective 'reliable' is preceded by the comparative word 'more', and together they form the adjective phrase modifying the noun 'car'.
