There are many different types of CC - Crowd Control - and LOL Wiki lays it out quite nicely
Loss of Control - Crowd controls are grouped into one of two categories depending on whether or not the effect removes total control of the player's character. Hard CC completely removes all control of a character, while soft CC only partially removes it.
Hard CC
- Airborne
- Forced Action
- Stasis
- Stun
- Suppression
- Suspension
Soft CC
- Blind
- Disarm
- Root/Snare
- Silence
- Slow
Disruption - Crowd controls are grouped into one of two categories depending on whether or not the effect disrupts a channeled ability (such as Karthus Karthus's Requiem.png Requiem and Katarina Katarina's Death Lotus.png Death Lotus). Hard CC will disrupt channels, while soft CC will not.
