What is the difference between 'since' and 'for'?
'Since' marks the starting point of a period — 'since Monday,' 'since 2010.' 'For' marks the length of the period — 'for three days,' 'for years.' Both often pair with the present perfect tense, but 'since' answers 'from when?' while 'for' answers 'how long?' Mixing them is a frequent mistake.
Can 'since' mean 'because'?
Yes. Besides marking time, 'since' can introduce a reason — 'since you're here, let's begin.' Here it works like 'because' or 'as.' Context makes the meaning clear: if it points to a moment in time, it is temporal; if it explains why, it is causal.

'I have lived here since 2015' shows the time sense, marking when the situation began and implying it still continues. 'She hasn't called since Tuesday' works the same way. In each case, 'since' fixes a point in the past and stretches forward to the present moment.
