This doubling of the ‘k’ serves a critical function: it signals that the preceding vowel is short. Compare make (long ‘a’, silent ‘e’ rule) with brick (short ‘i’, ‘ck’ indicates the short sound). This rule is so powerful that it effectively prevents a single ‘k’ from appearing at the end of a word following a short vowel in most native English words.

3. **It is a proper noun or
