Correct spelling, explanation: permitting comes from the base form permit, which has its origin in the Latin form permittere. It combines two other Latin words, which are per and mittere. The former means through while the latter means to send or let go. Permitting entered English in the times of the Middle Ages and it meant handing over. Today, permitting is either the present participle form of the verb permit, but it also functions as a noun or as an adjective.

Permitting the use of alcohol at a business meeting with a new client wasn’t a good decision as some people drank too much, which didn’t look good.

Incorrect spelling, explanation: the base form of permitting, which is permit, features a single -t letter. However, the rule says that when we add the -ing letter to a verb that ends with a vowel and a consonant, we need to double that consonant. Nevertheless, English users tend to forget about it and they spell permitting as permiting, which is wrong.
