Is a an common noun

Answer 1

The word 'a' is not a noun.

The word 'a' (and 'an') is an article.

An article is a word placed before a noun to give information about that noun:

• The indefinite articles 'a' and 'an' are placed before a singular noun to indicate that the noun is a general word for a person or thing.
• The definite article 'the' is placed before a singular or plural noun to indicated that the noun is a specific person(s) or thing(s).

The indefinite article 'a' is placed before a word that starts with a consonant sound, for example:

• a cat
• a fluffy cat
• a boiled egg
• a very old egg
• a red apple

The indefinite article 'an' is placed before a word that starts with a vowel sound, for example:

• an egg
• an ostrich egg
• an apple
• an angora cat
• an angry cat
