Etymology

Origin of left

First recorded in 1125–75; 1935–40 left ¹ for def. 6; Middle English left, lift, luft, Old English left “idle, weak, useless,” Kentish form of lyft- (in lyftādl “palsy”); cognate with Dutch, Low German lucht; akin to Middle English libbe (modern dialect lib ) “to castrate,” cognate with Dutch, Low German lubben

Explanation

If you are holding a compass and facing north, the direction to the west of you is also to your left. Left is the opposite of "right." People who are left-handed write with their left hands. and when you take a left turn on your bike, you should signal by holding your left arm straight out to the left. When left is an adjective, it has a completely different meaning: something that's left on the table, or remaining there, will probably be thrown away by your waiter. The Old English root is luft-, "weak," as most right-handed folks are weaker on their left sides.
