Kings and queens wear crowns. These three words are all pronounced with /k/ sounds at the beginning, but they are all spelled differently. Do you know why? We will start with the letter c, which is the most common letter used for this sound in English.

The letter C

1. Single C

Corey is a very active cat! As you can see, the letter c can come almost anywhere in the word. It is used for a /k/ sound before consonants and the vowels a, o, and u. The single c is the most common letter used for this sound. Here are some common examples:

• actor
• corn
• bacon
• direct
• carry
• picture
• culture
• pelican

2. Double C

People have parties to celebrate special occasions. As you learned in Lesson 1 of this series about the "magic" e, a single consonant between two vowels can mean that the first vowel is pronounced with a long sound instead of a short sound. If the word needs to contain a short vowel sound before the /k/ sound, we can double the c in the middle of the word. Here are some more common words with a double c pronounced with a /k/ sound after a short vowel sound:

• account
• broccoli
• hiccup
• accurate
• occupy
• tobacco
• raccoon
• accuse

The letter K

Janet and Emily are very kind. They love to share. We saw above that the letter c is usually used for a /k/ sound before the vowels a, o, and u, but if the /k/ sound is before the vowels e, i, or y. (When the k comes before a y, it is almost always at the end of words.) Here are some common examples of the letter k for a /k/ sound before an e, i, or y.

• king
• make
• skin
• skill
• risky
• poker
• keep

The letter k is also used at the end of one-syllable words after any sound except a short vowel sound. For example:

• milk
• tank
• soak
• peek
• cork
• hawk
• look
• bark

The CK combination

Looking at the clock can be very stressful during a test! The ck combination is used at the end of a one-syllable word after a short vowel sound. Here are some common examples:

• pick
• luck
• pack
• stick
• wreck
• lick
• duck

We also use the ck combination after a short vowel sound and before a vowel e, i, or y. This is a little less common. Here are some examples:

• rocking
• picky
• lucky
• blackest
• picnicking

The QU combination

Eleanor wants to ask a question. The qu combination is also common in English, but it is important to remember that this has a /kw/ sound, not just a /k/ sound. It can have some different pronunciations, but this is the most common. The letter q is not written alone in English, but is always followed by a u. Here are some common examples of qu with a /kw/ sound:

• quiet
• squint
• squash
• queen
• quarter
• quack
• quiz
• square
• require
• quote
