Forsook a piece of land concealing animal (5)

I believe the answer is:

okapi

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

'animal' is the definition.
(African mammal)

'forsook a piece of land concealing' is the wordplay.
'OKAPI' is hidden within the letters.
But, I am not sure how the hidden word is indicated.

Can you help me to learn more?

(Other definitions for okapi that I've seen before include "beast from Africa" , "Native of Central Africa" , "They're wild in central Africa" , "Wild animal" , "Beast related to giraffe" .)

I've seen this clue in The Irish News.
