Double letters
After a short vowel, many consonants are written twice: ff, ll, ss and zz at the end of short words, ck for the /k/ sound, and doubles inside longer words like rabbit and little. Knowing when a letter doubles, and when it doesn't, is one of the first spelling rules children meet.
Example words
- off
- cliff
- bell
- hill
- kiss
- dress
- buzz
- back
- duck
- sock
- rabbit
- little
- better
- carrot
The rules in this pattern
"ck" written as "k"
At the end of a word, straight after a short vowel, the /k/ sound is spelled "ck": "back", "clock", "stick", "duck".
A double "r" in "-ference"
When the stress moves off "-fer" the "r" stays single: "reference", "preference", "transference".
One "r" where "-fer" doubles it
When the stress stays on "-fer" the "r" doubles: "referring", "referred", "preferred", "transferring".
One "l" where the stress doubles it
If the last part of the word is stressed, its last letter doubles before "-ing" or "-ed": control, "controlled"; patrol, "patrolling"; excel, "excelled".
One "n" in "beginning"
The stress is on "-gin", so the "n" doubles before "-ing" and "-er": "beginning", "beginner".
One "r" where the stress doubles it
If the last part of the word is stressed, its last letter doubles before "-ing" or "-ed": occur, "occurred"; deter, "deterred".
One "t" where the stress doubles it
If the last part of the word is stressed, its last letter doubles before "-ing", "-ed" or "-er": forget, "forgetting"; admit, "admitted".
A double "n" where the stress does not double it
If the last part of the word is not stressed, its last letter stays single: garden, "gardening"; open, "opened"; happen, "happened".
A double "r" where the stress does not double it
If the last part of the word is not stressed, its last letter stays single: offer, "offered"; enter, "entering"; wonder, "wondered".
A double "t" where the stress does not double it
If the last part of the word is not stressed, its last letter stays single: limit, "limited"; visit, "visiting"; benefit, "benefited".
