I believe the answer is:

epee

I'm a little stuck... Click here to teach me more about this clue!

'tent' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?

I don't understand how the remainder of the clue works.

Can you help me to learn more?

(Other definitions for epee that I've seen before include "Bit of fencing" , "Fencer's sword" , "Fencing blade" , "Sharp-pointed duelling sword" , "Narrow fencing sword" .)

I've seen this clue in The Times and The Sunday Times.
