Incorrect spelling

appologies

Incorrect spelling, explanation: this spelling is a mistake, because double p is not there in the original form apologia (Greek), and there is no need to add such a letter later due to any reason. Therefore apologies is correct (plural form of apology), and appologies is incorrect. Apologies as the word from Greek should be written with one p.


Correct spelling

apologies

Correct spelling, explanation: apologies is the plural form of the word apology, which comes from the Greek apologia, meaning defense. The Greek word was later taken to other languages, hence English apology and plural apologies (-s added to a word ending with y gives -ies ending). Appologies is incorrect because there is no need due to etymology or pronunciation to add another p.
