Since is a conjunction and adverb and for is a preposition and conjunction. Since is used to describe things in the past and their relation to other things or feelings, like "since I went to Pakistan, I have had a desire to learn Sindhi" or "since I won the lottery, my life seems more exciting". For is used for reasoning for the most part like "for the team to win, he must play well" or the book is used for teaching foreigners English". If you have any questions, feel free to ask!
