Do you want to end a noun with y with ies, or do you want to change y into I with es?

Do you want to end a noun with y with ies, or do you want to change y into I with es?

Go to y to add nice baby paper

When does Y in a word become ies? For example, enjoys is a direct addition of S

It ends with a consonant and Y. change y into I plus es eg: studies
Vowel plus y, direct plus s eg: enjoy plays

Please help me to summarize how to add s at the end of a common English word, such as hobby going to y to write I plus es

In general, add s, such as: girl -- girls, book -- books, add es to the words ending with s, SH, x, CH, such as: box -- boxes watch -- watches
Words ending with the consonant + y change y into I and add es, such as baby babies
Most of the words ending with f or Fe turn Fe into V, and then add es, such as: wife -- lives
Words ending with O can be eaten with ES, and words ending with O can not be eaten with s, such as: zoo -- zoos, potato -- potatoes
