Your guide to League of Legend's Acronyms (ALPHABETICALLY SORTED)
NOTE (Important: This mini guide is not meant to explain the usage of compounded words such as KYS or TTYL, look that up instead.)
This is my small guide to the specific abbreviations of League of Legends. This guide will be displayed in an alphabetically sorted, organized LIST.
First off, we must talk about some of the basics. Champions (the characters controlled by players) have many different stats that can be modified by items bought from a shop. Stats change and enhance the effects of a champion's abilities (think spells, cast by the player) These items DO NOT carry over between games, and are bought using gold that DOES NOT carry over between games.
AA: AUTO ATTACK. The attack every champion has, with varying range. Auto attacks are modified by ATTACK SPEED and ATTACK DAMAGE, to trigger faster and deal more damage, respectively.
AD: ATTACK DAMAGE. AD increases damage dealt by AUTO ATTACKs.
ADC: ATTACK DAMAGE CARRY. ADC is one of the roles in league, mainly characters that heavily invest in the offensive stats ATTACK DAMAGE and ATTACK SPEED.
AFK: AWAY FROM KEYBOARD. This is a term used by practically all online games, meaning the player has left their character in an idle position, and perform another activity "away from the keyboard".
