Letters and speech sounds are divided into two categories:
- Consonants sounds where the air is blocked by the lips, tongue, or throat before leaving the mouth
- Vowels sounds where the air is not blocked.
Vowels play a major role in both spelling and grammar. They also have a direct impact on how consonants are used, such as spelling words with double consonants. Consider the difference between hop and hope—which, as present participles, become hopping and hoping. The presence of the silent e at the end changes the rules for how to conjugate certain words.
Unlike consonants, every word needs at least one vowel. There are a small number of exceptions, which we explain below, but in general, this is the rule. In fact, the shortest words in the English language are one letter, and they’re both vowels: the article a and the pronoun I.
