help me explain this sentence,please

just a guess here but withought nancy nothing would be worth doing if he or she didnt have nancy ? HMM this is a good sentence to break down!!

hello there, Literally it means....the sentence is talking about Nancy,wherein If she doesn't exist or she's not around then the person who wrote this cannot do anything worthwhile or cannot do anything that is worthy..I believe it is an excerpt from a known book SILAS WARNER by George Elliot,story was also been played in theater arts.

It is something written at the time of presenting a gift or when doing a dedication to Nancy!The person gifting or making a dedication is writing this sentence fondly highlighting the importance of Nancy's contribution for his achievement.
