Correct spelling

around

Correct spelling, explanation: the correct form around derives from the word round with prefix a-. The meaning, therefore, derives from cycling, going in circles. The base word round is spelled with one r with no need to add another with the prefix. This is why arround is an incorrect spelling, and the correct one is around.

Incorrect spelling

arround

Incorrect spelling, explanation: double r in this case is unnecessary as the correct form around has its roots in round, which is spelled with one consonant r. First meanings of this word were connected to going in circles, and moving round. Arround is therefore incorrect, because we don’t double the r when adding the prefix here.
