You need to attach the statements
Among the following words, the choice that you need to double the final consonant before adding the suffix to the base word is, shop + -er. The word shop plus -er becomes shopper with the double consonant p. The rule applied here is that, if the word is only one syllable and ends in a vowel and consonant, double the last letter before the vowel suffix.
you would use a comma after.
example:
dear Mrs.Smith,
I was pleased to meet you.
sincerly, NK
