What do you think?

 

[tedmc]

1. There is a leak on the ceiling.
2. There is a leakage on the ceiling.

3. You should know your limits.
4. You should know your limitations.

I would use 1 and 3. The nouns in 2 and 4 are more general.

I don't find "a leak on the ceiling" natural at all. There's either a leak "in" the ceiling (ie in the pipes above the ceiling) or there are signs of a leak on the ceiling (ie a damp patch).

I'm in the habit of putting the word I'm talking about within quote marks. (You could also use italics or bold print.)

"Know your limits!" is a common expression. However, I am unfamiliar with the other one, and for that reason alone I wouldn't use it.

You asked the same question two different ways in the same sentence.
