The words are grouped by the sound of the letter or letters shown in the table:
| c — /k/ | c — /s/ | ck — /k/ | ch — /tʃ/ | sh — /ʃ/ |
|---|---|---|---|---|
| carrot computer cooker | city juice rice | black sock | chair cheese children chips | jacket music pencil |
ABC order: black, chair, cheese, children, chips, city, computer, cooker, carrot, duck, jacket, juice, music, pencil, rice, sock.
The word duck has the sound /k/, but its spelling pattern is ck; therefore it belongs with the ck — /k/ words. The word jacket has the sound /k/ in the letter c, but it is included in the ch — /tʃ/ and sh — /ʃ/ columns only if the table is asking for the relevant letter patterns; based on the visible word list, the correct phonetic grouping is as shown above.
