120 Rules of Grammer
RULE05: The general rule for usage of the phrase "one of the" is:
“One of the + PLURAL NOUN + that/who etc. + SINGULAR/PLURAL VERB”
(1) When the relative pronoun “who/that” is not used – i.e. if "one of the NOUNs" is actually the SUBJECT of the verb - then we use a singular verb.
Example :-
🟥 There are many birds on the tree. One of the birds is red. [“One of the birds” is used as the Subject] ✅
(2) When the relative pronoun “who/that” is used – i.e. if "one of the NOUNs" is not actually the SUBJECT of the verb - then we use a plural verb.
Example:-
🟥 She is one of the mothers who are really working hard to make both ends meet. ✅
(3)If the sentence follows the form, “The only one of the + PLURAL NOUN + WHO/THAT etc.”, a SINGULAR verb is required.
Example:-
🟥 Rina is the only one of the girls who has ever been to India. [Singular verb] ✅
