Spelling Notes

Let's look at 'billion'. The first syllable 'bil' is a closed syllable because it ends in a consonant ('l'), which makes the 'i' produce its short sound, as per Rule 29. The 'll' is a common spelling pattern after a short vowel in a closed syllable. Understanding how closed syllables work helps us predict the short vowel sound and the double consonant.

Breaking words down into their syllables and analyzing why a word is spelled the way it is will drive you to be a better all-around speller, not just learning this single word. This is what strong spellers do subconsciously.
