can you please help me? Does one "make a difference IN people's lives" or does one "make a difference TO people's lives"... big debate here!
Awaiting your kind advice.
Both. The meanings are very close, and overlapping in many contexts, but I'd say maybe there's a tiny difference: 'make a difference in' is general, 'make a difference to' is specific.
[COLOR="DarkRed"]I want to make a difference in people's lives. They should be free, happy, clothed and well-fed.
I want make a difference to people's lives: the village should have access to clean water.
