Use Of The A And An Questions
Yes, 'a' and 'an' can be used before words starting with 'r'. The choice between 'a' and 'an' depends on the sound that follows the article. 'A' is used before words that begin with a consonant sound, while 'an' is used before words that begin with a vowel sound. For example, we say "a rabbit" because the 'r' in "rabbit" is pronounced as a consonant sound, but we say "an apple" because the 'a' in "apple" is pronounced as a vowel sound.
