A frequentative form of kar- “do, make” glossed “keep on doing”, appearing in the Quenya Verbal System of the 1940s using the frequentative patterns described in that document (PE22/100, 109).

Neo-Quenya: Tolkien used different patterns in his later writings: see the entry on the Quenya frequentative for details. However, I think the old patterns can coexist with the new ones, and I would retain this verb for purposes of Neo-Quenya. I think cacarra- can also mean “*to continue”.
