a rough estimate/estimation


Senior Member
Hi all, is it true that both "a rough estimate" and "a rough estimation" are correct?

For example:

Please give me a rough estimate/estimation of the likely cost of the repair.

I think I usually hear people say "a rough estimate", but dictionaries seem to define the 2 words similarly (i.e. a rough guess).

    If there is a distinction, it's that 'estimation' ('in my estimation', 'including estimation of the cost') is the process and 'estimate' is the result. But there is much overlap.
