The secretary and treasurer (one person) resigned _his_ position. My comrade and friend (one person) gave me _his_ help.
+221.+ +But two nouns joined by _and_, that mean different persons or things, must be represented by a plural pronoun, thus+:
Marx and Engels (two persons) wrote _their_ call to liberty, the Communist-Manifesto. Men and women will struggle for _their_ freedom. Childhood and youth should have _their_ rightful joys.
+222.+ +Use the singular pronoun when the nouns are kept separate by the use of _each_, _every_, _many a_, or _no_.+
Each man and boy must do _his_ part. (Not _their_ part.) Every soldier and every officer must do _his_ duty. Many a city and many a village gave _its_ best to the army. No comrade and no Socialist will give _his_ consent to war.
+223.+ +If you have two singular nouns as antecedents, joined by _or_, or _nor_, use the singular pronoun+, thus:
Either Germany or France must abandon _its_ position. Neither Wilson nor Bryan kept _his_ promise to the people.
+224.+ +When you use a collective noun and are speaking of the collection as a whole, use a singular pronoun+, as:
The committee will make _its_ report. The audience was hearty in _its_ appreciation. The jury has returned _its_ verdict.
+225.+ +But if you are referring to the individuals of the collection separately, use a plural pronoun+; as:
The committee adjourned for _their_ dinner. The audience kept _their_ seats until the close. The jury argued until _their_ nerves were on edge.
+226.+ We sometimes speak of things as if they were persons, and so use either masculine or feminine pronouns in referring to them. Such objects are said to be personified. Thus, we say:
The sun his ceaseless course doth run. The moon sheds her silvery ray. Nature dons her robes of green.
Here we speak of the sun as though it were a man or possessing the qualities of a man and use the pronoun _his_. Then we speak of the moon and nature as though they were women and use the pronoun in the feminine form.
+227.+ +A pronoun must agree with its antecedent.+
+Use the subject form of the pronoun if the pronoun is the subject of the sentence.+
+Use the object form when the pronoun is the object of a verb or a preposition.+
