What does CDR mean in League of Legends?

Cooldown reduction

In League of Legends (LoL), items and abilities that grant cdr reduce a champion, item, or spell's cooldowns (cd). This allows you to use the affected abilities more frequently.

For example, Luden's Echo grants 10% cdr, meaning a champion can reuse their ult and other abilities 10% more quickly. You may also see cdr referred to as ability haste, because Riot renamed the cooldown reduction stat to ability haste in LoL version 10.23.
