I believe the answer is:

crash land

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

'come down' is the definition.
(thesaurus)

'roughly around reckless terrain' is the wordplay.
'roughly' becomes 'c' (circa).
'around reckless' becomes 'rash' (synonyms. I am not sure about the 'around' bit.).
'terrain' becomes 'land' (I've seen this before).
'c'+'rash'+'land'='CRASH-LAND'

Can you help me to learn more?

I've seen this clue in The Daily Express.
