newb question

By ssalo7, in A Game of Thrones LCG

Just got into the game this week. Not understating what some of the traits do for characters. tried to search for this answer but was unable to find it anywhere.what does it mean when a character gains the melee trait or a joust trait. As in the card.

Champion's Favour View Details
Type: Attachment House: Neutral
Cost: 1
Setup.
Attached character gains melee.
They fought with blunted weapons in a chaos of mud and blood, small troops fighting together and then turning on each other as alliances formed and fractured, until only one man was left standing.
Set: ODG

Thanks in advance
