africa

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

'it' is the definition.
The definition suggests a singular noun which matches the answer.

I can't explain the remainder of the clue.

Can you help me to learn more?

(Other definitions for africa that I've seen before include "Out of -, novel by Karen Blixen (filmed)" , "Always something new from it (Pliny)" , "Second largest continent" , "Land of Malawi and Mozambique" , "Continent (6)" .)

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