It may show interest in Paris for example (7)

I believe the answer is:

capital

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

'paris for example' is the definition.
(paris is a kind of capital)

I cannot understand how the rest of the clue works.

Can you help me to learn more?

(Other definitions for capital that I've seen before include "Major city - investment - excellent" , "Upper-case letter" , "Means" , "Topping" , "A great city - that's fine" .)

I've seen this clue in The Globe and Mail.
