14/15...word Ninja...thanks for the answers

Got 14. In our school, in Canada, we were always taught that the vowels were "a, e, i, o, u and sometimes y".

William Laughlin, *words spelled ONLY with vowels.

This quiz would have been a little better with a brief explanation for several of the answers such as the other words ending with "dous". In addition to hazardous, there are horrendous, stupendous, and tremendous! They could have mentioned the number of definitions for the word "set". I found at least 430 senses listed in the Second Edition of the Oxford English Dictionary, published in 1989. Examples of words with one vowel would have been interesting. I, a, io, eau, and iou.

Word ninja indeed. Good quiz, with answers this time. See, that wasn't so hard...

cwisconsin, it is “acting” as a vowel. Y is known as a semi-vowel in British English.

gusroy, not sure what you were taught in school, but in British English a y is called a semi-vowel and can “act” as a vowel in some situations. We never refer to it as a vowel.

Rhythms does have a vowel—sometimes y is a vowel!

12/15...word ninja...okay..
