Apostrophe for Singular Possessive

The Apostrophe

Rulebase Summary

Use an apostrophe and s to show possession in most singular nouns. This is the basic possessive rule — the apostrophe and s are added to the end of the singular noun.

Transcript Notes

BGGP allows no exceptions to the apostrophe s rule for singular possessives — always add apostrophe s regardless of the ending letter, number of syllables, or pronunciation. This eliminates inconsistency. Pronunciation cannot be the standard for the possessive form in reporting because different speakers may pronounce the same word differently.
