Crowd-Control

Crowd-Control, abbreviated as CC, is anything that causes an opponent to temporarily lose one, several, or all means of control over their own character. CC can be divided into two categories: Soft CC and Hard CC.

Soft CC
These types of CC include movement or attack speed slows as well as vision and hearing impairment. They're considered "soft" because they don't cause you to lose complete control over your character, but rather dampen your capabilities temporarily.

Examples:

Hard CC
These types of CC include knockdowns, stuns, and snares. They're considered "hard" because they cause you to completely lose control for the duration of the effect. Snares are not as serious as stuns or knockdowns because you can still use ranged attacks while snared, however, the loss of movement is serious enough to be in this category.
