The addition of a Y to a name or noun may be a diminutive (doggy, puppy) or it can make the noun into an adjective, meaning "having the same attributes." Where an E is present, it may be dropped.
Examples:
horse - horsey, jaunt - jaunty, health - healthy
(dropped E) spice- spicy, ease, easy, whine- whiny,
(double letter) fin - finny, fun - funny
Because that's just how they type or they like to do that.
you need to double the consonant and add er
Some words that end in the vowel y and add es to form the plural are alley, journey, and key.

Monosyllabic words ending in -y add -s: fay - fays day - days Plus, words ending in y that are being cited as words remain unchanged: my - mys (or my's) Otherwise, the main exception to this rule is personal proper nouns, which retain the "y" and add "s"; this is common with people's last names: Kelly - Kellys Kenndy - Kennedys etc. In addition, many words ending in -ey sometimes the -ey and add s: storey - storeys (also stories) etc.
