No, two forms of the same root.

         CasCade=  Falling, then Falling (smaller, plurally)  further
  i guess  MainTain  is sort of like that.
 

  from Latin manū (“with/in/by the hand”, ablative of manus) + tenēre
(“to hold”).

 Manipulate,  "manoeuvre" (or "maneuver" in American English)
  Others?   (Same Root  twice) ???

I can't think of another European example. But in the languages I work on (Oceanic), formation of a word by reduplication (repeating the same root) is common. Most often it just refers to multiple events  -- so "fall-fall" would mean falling again and again, or many things falling. But the reduplicated word may take on a distinct meaning, e.g. in Polynesian languages /kau/ 'to swim', /kaukau/ 'to bathe'.
