The rule ir
Regular plural endings in English often include adding "-s" (e.g. cats, dogs), "-es" (e.g. foxes, classes), or "-ies" (e.g. cherries, babies) to the singular form of a noun.
Use an ''s' when you are indicating possession. Use 'ies' when you are indicating plurality.
Use 's to make a singular noun possessive (e.g., dog's bowl) and use -ies to pluralize a singular noun ending in a consonant and -y (e.g., babies).

The basic rule is for nouns ending in 'y' preceded by a consonant, the plural is formed by dripping the 'y' and 'ies'. For nouns ending in 'y' preceded by a vowel, the plural is formed by adding 's' only. Why this came about, I do not know. Perhaps a question for the category 'word origins'.Some examples for nouns that drop the Y and add IES for plurals are:babiesdaisiesladiesstoriesdairiesfairiespartiescountriesSome examples for nouns that do not drop the Y for plurals:alleysboyschimneysdaysessaysjoyskeysmonkeys
The spelling rule is: when the word has a vowel (a, e, i, o, u) before the letter ‘y’, you add the letter ‘s’ and when the word has a consonant (b, c, d, f, g, h, j, k, l, m, n, p, q, r, s, t, v, w, x, y, z) before the letter ‘y’, you remove the ‘y’ and replace it with ‘ies’.
Use an ''s' when you are indicating possession. Use 'ies' when you are indicating plurality.
