'It makes me more proud since my family'. Please tell me about "since"?. What is meaning of since?
Yes, the sentence is incomplete. The only thing that comes to mind is "since"="because".
OK there is a full context.
“I am proud of the fact that I inaugurated the construction of the historical building named after great leader of the 20th century, that is, the Quaid-i-Azam. It makes me more proud since my family’s Syed Zainul Abideen Gilani and my father Syed Alamdar Hussain Gilani were workers of the Quaid.
It means because/as.
