When adding an ending to a word that ends with y, change the y to i when the y comes after a consonant:

			Fairy - Fairies
			Carry - carries
			Carry - carried
			Empty - emptiness
			Marry - marriage
			Easy - easily
			Lucky - luckier

If the ending you want to add begins with the letter i the y does not change, e.g. - ing, - ish, - ism

			Carry - carrying
			Thirty - thirtyish
			Crony - cronyism

When adding an ending to a word that ends with y, make no change if the y comes after a vowel:

			Pay - paying
			Obey - obeyed
			Toy - toying
			Buy - buying

Note the following exceptions to this rule:

			Say - said
			Pay - paid
			Lay - laid

When adding an ending to a word that ends with ie, change the ie to y before -ing:

			Lie - lying
			Die - dying
			Tie - tying
