Noun/Adjective Suffixes:

Suffixes modify the meaning of the base word and can be used to form adjectives from nouns and vice versa.
Suffixes can be used to form diminutives, augmentatives, and pejoratives (depreciatives), but they should be coined cautiously: many have preexisting figurative, slang, or sexual meanings.
Many other suffixes form adjectives from nouns and verbs, but most of these adjectives can stand alone as nouns -- the noun they modify can be an unspoken indefinite pronoun: one or some.
