Question

If the singular of a word ends in an s-sound or its plural makes an extra s-sound, simply add an _____ to form the plural. ies es s apostrophe s ('s)

Answer 1

Answer:

If the noun is plural, just attach an apostrophe. If the noun ending in s is singular, most sources recommend adding both the apostrophe and an additional s. In these cases, the apostrophe + additional s adds another syllable to the pronunciation. If the extra syllable sounds unnatural, add just the apostrophe.
