“Support” vs “Help”: What’s the Difference?

Help usually means direct, hands-on assistance — you help someone carry bags or help a friend move house. Support is broader: it includes emotional backing (“support a friend through grief”), financial aid (“support a charity”), physical bearing (“the wall supports the roof”), and approval (“support a candidate”). You can support without lifting a finger — by donating, voting, or simply believing in someone. In short: all helping is a kind of support, but not all support is hands-on help.
