plural es

Rule Core

Plural -es is added to nouns ending in s, x, z, ch, or sh. These sounds require an extra syllable for smooth pronunciation, e.g., glass → glasses.

Pronunciation Guide

-es is pronounced /ɪz/. Finish the base consonant, then add a short vowel /ɪ/ followed by a voiced /z/. Airflow should remain smooth and continuous.

Word Analysis

sunglasses is always plural in form. The ending -ses is pronounced /sɪz/, preventing an awkward consonant cluster.

Pitfall Alert

Do not pronounce -es as /s/. Also avoid adding -es to words that do not end in sibilant sounds; focus on sound, not spelling.
