C. of + noun is used for possession
1. When the possessor noun is followed by a phrase or clause:
I met the wife of the man who lent us the money.
(the underlined expression is too long to be followed be ’s)
2. With inanimate ‘possessors’, except those listed in A above:
the walls of the town the roof of the church
However, it is often possible to replace these expressions by the others:
the town walls the church roof
The first noun becomes an adjective and cannot be plural:
the roofs of the churches = the church roofs
Unfortunately these replacements are not always possible so it is
recommended to use of when in doubt.
ADJECTIVES
An adjective is a word which tells us more about a noun and is used when we describe people, things, events, etc. We use adjectives before nouns and after some verbs.

1. Kinds of adjectives

a) Demonstrative: this, that, these, those
b) Distributive: each, every, either, neither
c) Quantitative: some, any, no; little, few; many, much; one, twenty
d) Interrogative: which, what, whose
e) Possessive: my, your, his, her, its, our, their
f) Of quality: clever, dry, fat, golden, good, heavy, square

2. Participles used as adjectives

Both present participles (ing) and past participles (ed) can be used as adjectives. But be careful not to confuse them. Present participle adjectives, tiring, boring, interesting, are active and mean ‘having this effect’. Past participle adjectives, tired, bored, interested, are passive and mean ‘affected in this way’. In other words, someone is -ed if something (or someone) is -ing. Or, if something is -ing, it makes you -ed.
Jane is bored because her job is boring.
Jane’s job is boring so Jane is bored.
Other pairs of participle adjectives are:
amusing amused exhausting exhausted
amazing amazed frightening frightened
annoying annoyed horrifying horrified
confusing confused shocking shocked
depressing depressed terrifying terrified
exciting excited worrying worried
