More about Vowels
- The word Iouea (a genus of sea sponges) contains all five vowels and no other letters. (Being the name of a genus (i.e., a proper noun), it is written with a capital letter. Also of note, it is the shortest word with four syllables.)
- The words abstemious and facetious contain all five vowels in order.
A vowel sound (but not necessarily a vowel in the actual spelling) will be present in a syllable.
Why Should I Care about Vowels?
Should you write "an" or "a"?Use an (not a) before a vowel sound. The important word here is sound. (The ruling is not use an before a vowel.)
- an apple. a apple. ( An is correct because apple starts with a vowel sound (and a vowel for that matter).)
- an RTA. a RTA (An is correct because RTA starts with a vowel sound (ar), even though the first letter is not a vowel.)
- An unidentified man with a unicorn tattoo rented a house an hour ago. (Even though they start with the same three letters, unidentified and unicorn attract different indefinite articles. Similarly, hour attracts an while house attracts a. It's all about the sound of the first letter.)
- Becoming a eunuch wasn't a one-off deal – it was a two-off deal. (Eunuch and one-off start with vowels but with consonant sounds.)
