Incorrect spelling


Incorrect spelling, explanation: quaterly is the incorrect form of an adverb because the consonant r is missing after the vowel a. The users of English may make this mistake because of its pronunciation. In the UK the consonant r, occurring at the end of the syllable, is not heard. But the correct spelling of this word is with r as quarterly not quaterly.
