The best way to spell English words correctly is to consult your dictionary frequently. The spelling rules are difficult, and the exceptions to the rules are too numerous.
Readers who want to examine a serious set of English language spelling rules can find a set in Webster's Seventh New Collegiate Dictionary starting at page 1187.
Vowels are certain letters in the English alphabet. The vowel letters are (a, e, i, o, and u). The letter (y) may occasionally function as a vowel. All other letters in the English alphabet are consonants.
Vowels and consonants are determined by human anatomy. The vowels can be pronounced without restriction of the airflow through the larynx (voice box). We restrict air flow through the larynx when we pronounce consonants. That difference affects the way we pronounce words, and consequently, the way we spell words.
The words examined below can cause problems because of similar spelling, because pronunciation is similar or because of confusion regarding the meaning of the words.
