is saying this right:
That house is theirs.
is this sentence correct
either alan or john will collect signatures for THEIRS petition on tuesday
or is it HIS
The correct word in this sentence is HIS.
The construction of "either . . . or" is singular so a singular pronoun is used.
However, if the subject was plural and said, then --
Alan and John will collect signatures for THEIR peitition on Tuesday.
is it his
