Typically, when a word ends in a consonant followed by a y, you change the y to i and add es to form the plural or third person singular form. For example, "baby" becomes "babies." However, when a word ends in a vowel followed by a y, you simply add s to form the plural or third person singular form. For example, "monkey" becomes "monkeys."
Some words that end in the vowel y and add es to form the plural are alley, journey, and key.
For nouns that end in a consonant + 'y', you need to drop the final 'y' and add '-ies' to form the plural. For example:baby > babiesgallery > galleriescandy > candiesfly > fliesparty > parties
Valleys ... because if the noun ends in y + a,e,i,o,u ( a vowel letter) as in boy (y+o) you do not cross out the y and add ies, you only add (s): boy+boys.... day =days, BUT if the noun ends in y+ a consonant letter (b,c,d....), we cross the (y) and add "ies", as in baby=babies... lady=ladies
The plural form of "y" is "ys" or "ies," depending on the context.
Change the y to i and add es. For example, baby becomes babies.
Plurals
Lobotomies... To pluralize a word which ends in a "y" drop the "y" and add "ies".

The spelling rule is: when the word has a vowel (a, e, i, o, u) before the letter βyβ, you add the letter βsβ 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 βyβ, you remove the βyβ and replace it with βiesβ.
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

Words that drop the ending "y" and add "-ies" are those for which the penultimate letter of the word is a consonant. As the penultimate letter of keys is a vowel, the final consonant y is retained and an s is added at the end.
