Correct spelling

asks

Correct spelling, explanation: asks is the correct form of third-person singular of the verb ask, because to create such a form we need to add -s to the verb. Here, the verb ends with k to we add s regularly, with no other letters. Therefore asks is the correct spelling and askes is wrong.

Definition of asks:
verb, third-person singular of ask, to inquire, to request
Katie is 4 years old and often asks her mum funny questions.
He always asks his parents if he can go outside with his friends.


Incorrect spelling

askes

Incorrect spelling, explanation: askes is incorrect as we do not need to add an extra e when we create 3rd person singular of the verb ask. This form is created in a regular way – we only add e in case of s, ss, sh, h, and ch endings, so askes is an incorrect form and asks is the correct one.
