When pluralizing words ending in sibilant sounds, which ending is most often added?

When pluralizing words that end in sibilant sounds, the most common practice is to add "es" to the base word. Sibilant sounds include those such as /s/, /z/, /sh/, /ch/, and /j/, which create a hissing or whistling sound. For instance, the word "wish" becomes "wishes," and "buzz" turns into "buzzes." Adding "es" helps maintain the proper pronunciation and flow of the word, making it easier to articulate the plural form distinctly.

The other endings have different uses; for example, "s" is generally used for pluralization of words that do not end in these sibilant sounds, while "ies" is specifically associated with changing nouns that end in a consonant followed by "y" into plural forms. Additionally, "ed" is used for creating past tense verbs and does not pertain to pluralization at all. Therefore, "es" is the appropriate ending for pluralizing words with sibilant sounds, ensuring both correct grammatical function and ease of pronunciation.
