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

'restore energy' is the definition.
'invigorate' can be an answer for 'restore' (thesaurus). I'm not certain of the 'energy' bit.

'give ration out' is the wordplay.
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'give'+'ration'='giveration'
'giveration' anagrammed gives 'INVIGORATE'.

'to' acts as a link.

Can you help me to learn more?

(Other definitions for invigorate that I've seen before include "Perk up" , "Give energy to" , "Give strength to" , "Strengthen" , "Liven up" .)

I've seen this clue in The Daily Express.
