ck = k

Core Rule

ck = /k/ is a positional spelling rule. After a short vowel at the end of a syllable, English prefers ck to represent a strong /k/ sound. It represents one sound, not two.

Articulation Guide

/k/ is a voiceless stop. Raise the back of the tongue to the soft palate, build air pressure, then release sharply. Lips are relaxed; vocal cords do not vibrate.

Word Analysis

• lick /lɪk/: short vowel /ɪ/ requires ck to close the syllable.
• socket /ˈsɒkɪt/: stressed syllable with a short vowel uses ck.

Pitfalls

ck never starts a word. After long vowels or diphthongs, use k or ke, not ck.
