Spelling help
Remember that jewel ends in a single l. The related words jewelled, jewellery, and jeweller follow the usual rule that you should double the l when adding endings which begin with a vowel to words which end in a vowel plus l (the spellings jeweled, jewelery, and jeweler are American).
