My brother's name is Christopher.
To sign this, start by signing 'MY', 'BROTHER', and 'NAME'. Then, carefully fingerspell C-H-R-I-S-T-O-P-H-E-R. Remember to keep your hand steady and maintain eye contact while spelling to ensure the name is clearly understood by the person you are talking to.

Is Christopher coming to the party?
Fingerspell C-H-R-I-S-T-O-P-H-E-R, then sign 'COME' and 'PARTY'. Since this is a yes/no question, make sure to raise your eyebrows and lean slightly forward at the end of the sentence to indicate you are asking a question.

I met Christopher yesterday.
Begin by signing 'YESTERDAY', then point to yourself for 'I', sign 'MEET', and finally fingerspell C-H-R-I-S-T-O-P-H-E-R. Make sure your fingerspelling flows smoothly at the end of the sentence without rushing the letters.
