The word "AVIR" is typically pronounced as [əˈvɪr] in IPA phonetic transcription. The spelling of this word can be explained using the principle of the English language known as "i before e, except after c." The "i" comes before the "e" in this case because "AVIR" does not follow the "c" rule. The vowel sound is pronounced as a short "i" sound, and the final "r" is silent. Proper spelling is important for communication and understanding in written language.
