Correct spelling, explanation: bodies is a plural form of the noun body, which comes from Middle English bodi and from Old English bodig. It’s also related to Old High German botah. It was created by adding the suffix -ies to its root. Why? Because of an important rule: when there is a consonant before the letter -y in a word and we want to create a plural of it, the additional ending must be -ies, not -s. Therefore, the only correct spelling is bodies, not bodys.

Definition of bodies:
plural noun, the whole physical structure of a human or animal
The bodies of my friends were really muscular.
I think my parents should nourish their bodies with healthy food.

Collocations with bodies:
Some most commonly used collocations include: female bodies, male bodies, bodies, minds and souls, bodies of work, and bodies of water.

Incorrect spelling, explanation: this spelling is not correct, because when we want to create a plural from a noun – in this case, it’s the word body – in which the last two letters are a consonant and -y, we need to change -y to -i and add -es. The form bodys does not follow this rule, therefore the only correct version is bodies.
