The spelling of the word "BEAV" is peculiar and may raise questions. However, it can be explained through phonetic transcription. The pronunciation of "BEAV" can be written as /bi:v/ which consists of two syllables. The first syllable is a stressed, closed syllable represented by the letter "b." The second syllable is an unstressed, open syllable represented by the letters "eav." The letter "e" in "eav" can be pronounced as the long vowel sound /i:/, hence the letters "ea" are used together to signify this sound.
