Incorrect spelling


Incorrect spelling, explanation: askes is incorrect form because we don’t add es ending to a verb in the third person singular unless this verb ends with s, ss, sh, h or ch. This means we will add only -s to ask, so we receive asks. This rule points to asks as the correct form.

Correct spelling


Correct spelling, explanation: this form, asks, is correct because in the case of k at the end of the verb we don’t need to add es ending for 3rd person singular, only s. -es ending is added when a verb ends with one of the following: s, ss, sh, h and ch. Therefore asks is the correct form and askes is incorrect.
