An adjective (abbreviated adj.) is a word that describes a noun or noun phrase. Its semantic role is to change information given by the noun.
Traditionally, adjectives were considered one of the main parts of speech of the English language, although historically they were classed together with nouns. Nowadays, certain words that usually had been classified as adjectives, including the, this, my, etc., typically are classed separately, as determiners.
Here are some examples:
- That's a funny idea. (attributive)
- That idea is funny. (predicative)
- Tell me something funny. (postpositive)
- The good, the bad, and the funny. (substantive)
