Use Of The A And An Questions Medium
The use of "a" or "an" before words starting with a "w" sound depends on the actual sound that follows the "w" sound.
If the word following the "w" sound begins with a vowel sound, then you should use "an." For example, "an apple" or "an owl."
However, if the word following the "w" sound begins with a consonant sound, then you should use "a." For example, "a whale" or "a wolf."
It is important to note that the decision is based on the sound that follows the "w" sound, rather than the actual letter.
