Spelling Notes

Let's break down 'computer' into its syllables: 'com-pu-ter'. Notice that the 'o' in the first syllable 'com' makes a weak 'schwa' sound (ə), which is common for vowels in unstressed syllables, as explained in Rule 28a. This means the 'o' doesn't make its usual long or short sound, but rather a softer, almost 'uh' sound. The 'u' in 'pu' makes a long 'oo' sound, and the 'er' at the end is a common suffix. Understanding how unstressed vowels can make the schwa sound helps explain why the 'o' in 'computer' is spelt that way, even though it doesn't sound like a typical 'o'.

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.
