Nouns and Adjectives
In English, nouns can function as adjectives though, if there is a common adjective, use that, e.g. the cricket match.
Adjectives generally cannot function as nouns.
e.g. my book, your story, his leg, its tail, our house
In the ending of a letter, note the reference to the writer’s name:
Looking forward to hearing from you,
NB. “Looking” is a present participle, present participles are partly a verb and partly an adjective and, as an adjective, present participles have to refer to a noun which, in the ending of a letter, is the writer’s name.
