‘One of My Friend’ or ‘One of My Friends’?The plural-noun, singular-verb rule

‘One of’ is one of the most frequently tested subject-verb agreement patterns in SSC exams — because it breaks the instinct that a plural noun needs a plural verb. Here is the rule, permanently.

The rule in one line

One of + plural noun + singular verb.
‘One of’ means ‘one member selected from a group’ — the group must be named with a plural noun (friends, students, candidates). But the real subject of the sentence is ‘one’, which is singular, so the verb stays singular too: One of my friends is coming.

The family — same pattern every time

Each ofsingularEach of the students has a laptop.
Either ofsingularEither of the roads leads to the station.

💡 Memory line: whatever comes right after ‘of’ is plural; the verb agrees with the word before ‘of’, which is always singular.

Five exam traps — solved

Each sentence below is a real SSC error-spotting pattern. Find the error before opening the answer.

Trap 1singular noun after 'one of'One of my friend is coming to the party.+

One of my friends is coming to the party.

'One of' means 'one member out of a group' — the group must be named with a plural noun. 'Friend' is singular here, which is the error. The verb 'is' is already correct, because it agrees with 'one', not with the group.

Trap 2plural verb with 'one'One of the students have submitted the assignment late.+

One of the students has submitted the assignment late.

The noun 'students' is correctly plural — that part is fine. The error is the verb: it must agree with 'one' (singular), not with 'students'. 'Has', not 'have'.

Trap 3plural verb with 'each'Each of the boys were given a prize.+

Each of the boys was given a prize.

'Each of' follows the identical pattern as 'one of': plural noun ('boys'), singular verb. 'Were' wrongly agrees with 'boys' instead of with 'each'. The correct verb is 'was'.

Trap 4plural verb with 'neither'Neither of the two candidates were selected for the interview.+

Neither of the two candidates was selected for the interview.

'Neither of' also takes a singular verb, even though it is immediately followed by a plural noun ('candidates'). Examiners plant 'were' here because it sounds like it agrees with the nearby plural noun — it doesn't.

Trap 5singular noun after 'one of' (possessive)One of my sister's friend called me yesterday.+

One of my sister's friends called me yesterday.

The possessive 'my sister's' doesn't change the rule — 'one of' still needs the group noun in its plural form: 'friends', not 'friend'.

Frequently Asked Questions

Is it 'one of my friend' or 'one of my friends'?+

'One of my friends' is correct. 'One of' means 'one member selected from a group', so the noun naming that group must always be plural: friends, students, boys, candidates. Saying 'one of my friend' leaves the group as a single person, which contradicts the meaning of 'one of'.

Why does 'one of my friends' take a singular verb like 'is'?+

Because the grammatical subject of the sentence is 'one', not 'friends'. 'Of my friends' is just a prepositional phrase describing which group the 'one' comes from. Since 'one' is singular, the verb must be singular too: 'One of my friends is coming', not 'are coming'.

Do 'each of', 'either of', and 'neither of' follow the same rule?+

Yes. 'One of', 'each of', 'either of', and 'neither of' all follow the identical pattern: plural noun after 'of', singular verb agreeing with the first word. 'Each of the students has', 'Neither of the candidates was' — the logic never changes.

What is the SSC exam trap with 'one of'?+

Examiners plant one of two errors: either a singular noun where a plural is required ('one of my friend'), or a plural verb where a singular is required ('one of the students have'). Both traps rely on the same underlying rule, just tested from opposite ends.
