Correct spelling


Correct spelling, explanation: the adverb around was created by combining the prefix -a with the adjective round, its root. There’s no reason to spell it with double -r. It’s often used to describe a location. Remember that the only correct version of this word is around, not arround.

Definition of around:
adverb, located or situated on every side
A crowd had gathered around the scene of the accident.
I had a scarf around my neck.

Incorrect spelling


Incorrect spelling, explanation: adverbs are derivatives of adjectives and this word is no different. That’s why we must look at their roots if we want to create new forms. In this case, the basis is round – with a single -r consonant. The right form, around, is a combination of two elements – -a prefix and a root. You can’t spell it any other way, therefore arround is incorrect.
