Question

Which plural is spelled incorrectly? journeys dishes sheeps colonies

Answer 1

The answer to your question is Sheeps.

This is because the plural of sheep, is still sheep.
Ex. There are 5 sheep on my farm.

Hope this helps!

Answer 2

The second alternative is correct (B).

The reason for this confusion is at the origin of the word.

Sheep is a word originated in the oldest Germanic language. For a random reason, this noun does not mark its plural with the addition of the "s", so that there is no explanatory rule, we must remember.
