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

'get to grips with' is the definition.
(I've seen this before)

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

(Other definitions for engage that I've seen before include "Morally committed to" , "Employ or get involved in battle" , "Secure" , "Take into service or commit to marriage" , "Take on (eg for work, in battle)" .)

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