Clue: Provide a lift prior to work or lecture (4,2,4)
Answer: TAKE TO TASK
Explanation: Definition: lecture
**TAKE TO** ("provde a lift") prior to **TASK** ("work") 
*I'm not sure this clue works or if my parsing is wrong here, as "take to" would be synonymous with "give a lift to", but I can't use the "to " in the clue as it is part of "prior to".*
