what is the meaning of assasin? what do they do in game? same question for carry?

An assasin sneaks past the tank (or jumps) and ignores him completely to go straight for the enemy squishies in the back (the carry). They do a lot of "Burst" damage, all damage at once.

You have two types of carrys, The AP carry (mid lane), which is stronger in the beginning, and the AD carry (bot lane), who needs a lot of gold and is stronger in the end part of the game.
A carry does the damage, but cant stay alive on its own.

An assasin can also be the carry.

For a better definition, check the dictionary: http://euw.leagueoflegends.com/board...d.php?t=445109

is caitlyn ap or ad? as i use her most

.......ad???

If you take a look at all the champions labled as "Assassin", you'll notice that they have no or very little aoe attacks, because they specialise in 1v1 combat. An Assassin's job in a teamfight is to kill the enemy carries as quickly as possible.

why call carrys carrys tho lol

They carry the team to victory. Carry means: To take from one place to another; transport.

they do all the damage, the others support the carry, so the carrys can do their business without being killed. Thats why tanks and supports dont get kills, or shouldnt get kills, because if the carry is fed, the game is won (for a big part).

ha is that why when i play cho gath i get like 1 kill 8 deaths n bout 10 assists!
