Spelling the /k/ sound before a vowel :
is it c or k ?

spell c or k before a vowel? spell c or k before a vowel?
Why is it c in cat but k in kitten?

Teaching point The most common spelling choice for the /k/ sound is the letter c but sometimes we need to use k.


[The symbol /k/ is used to show this sound. The letter c can often say /s/ (as in cent, city, cycle) so it could be confusing to use it to show a sound. K always has the sound /k/.]

There are some rules to help with the spelling choices for the /k/ sound:

1. If the next vowel is a, o or u, we usually use c.
Examples:

call, carrot
copy, colour (US color)
cup, cucumber



2. If the next vowel is e or i, we usually use k.

Examples:

keep, kettle
kill, kitchen

There is a good reason for this rule:
When c is followed by e or i, it will make the sound /s/ as in cent and circle. So, if you want the sound /ke/ or /ki/, you must use k.




3. If the next letter is a consonant e.g. r or l , we almost always use c. Examples:

crab, cricket
close, clap
