Incorrect spelling

get’s

Incorrect spelling, explanation: an apostrophe before s is used only with nouns: to express possessiveness or to shorten verb is or has). Get is a verb so it can’t be used in these contexts. Gets however is a third person singular from the verb get, as we add s to verbs in such case. Therefore gets is the correct form here, and get’s is incorrect.


Correct spelling

gets

Correct spelling, explanation: this form is correct since third person singular form from get is gets (we add s to the verb). S after an apostrophe is used either for possessiveness or to abbreviate verb be (is) or have (has) after a noun. Get is a verb so these two option do not apply to it.
