perturb, imperturbable, turbid, turbulence...

Perturb (V): Disturb gently.
“Per” means “thoroughly” and “turbare” means “to disturb” which comes from “turba” which means “confusion.” .So to perturb somebody means to disturb him completely or thoroughly. Another cognate for this word is imperturbable.

Synonyms (N): Disturb, disquiet, discomfort, vex, agitate, muddle, and jumble.

Example: Just few minutes after the lecture started he was able to attain a state of nirvana such that nobody including his teacher was able to perturb him.

Imperturbable (Adj): Calm; placid.
“im” means “not” and perturb as we have seen means to disturb. So something that is imperturbable is a characterized by being calm and placid.

Example: His usual imperturbable face belied his agitated mind on that day.

Turbid (Adj): Muddy; having sediment distributed.
It is derived from Turbidus, which means full of confusion. Turbidus comes from the same root “turba” i.e. confusion.
