Every pronoun decision
Which pronoun, in which form, pointing at what? The five choices every pronoun makes you settle.
A pronoun you write can go wrong in five ways, so check five things. Is it the right type for the job? A reflexive like myself only works when the action bounces back to the subject of its own clause. Can the reader tell which noun it points back to? If two nouns could fit, or none does, name the noun instead. Does it agree in number with that noun, and stay in the same person? Everyone is singular (singular they is accepted), and a team acting as one unit takes it. Is it doing the action or receiving it? The subject form (I, he, who) does it; the object form (me, him, whom) receives it or follows a preposition, and dropping the other person from a pair tells you which. Last, the spelling: an apostrophe marks a contraction (it's, they're, you're), never ownership (its, their, your).
Which type of pronoun?
Seven families by job, personal, possessive, reflexive, demonstrative, interrogative, relative, and indefinite.
Example
Refers to no one in particular; everyone, somebody, and nobody are singular.
Please contact me with questions, not myself.
Which noun does it point to?
Term
antecedent
The noun the pronoun stands in for; the reader has to be able to find it.
Example
Two nouns could fit, so name the one you mean.
Singular or plural?
Example
A singular noun takes a singular pronoun; singular they is accepted for a person.
Example
A group acting as one unit takes it.
Subject form or object form?
Example
The pronoun's job in its own clause decides; doing the action takes I, he, who, and receiving it or following a preposition takes me, him, whom.
Apostrophe or not?
Term
homophone
Example
Its/it's, their/they're/there, your/you're sound alike; the apostrophe marks a contraction, never ownership.
