The letter w represents both a consonant and the vowels and - a preceding definite article will reflect this by following the rules above, e.g. "the wall" but or "the egg". However, pre-vocalic is used before both the consonantal and vocalic values represented by i, e.g. "the hen" and "the anguish". It is also always used before the consonant h, e.g. "the summer".
