indebted

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

'owing recognition' is the definition.
'indebted' can be an answer for 'owing' (thesaurus). I am not certain of the 'recognition' bit.

'absolutely but empty inside' is the wordplay.
'absolutely' becomes 'indeed' (I've seen this before**).
'empty' suggests removing the centre.
'inside' indicates putting letters inside.
'but' with its centre taken out is 'bt'.
'indeed' going around 'bt' is 'INDEBTED'.

Can you help me to learn more?

(Other definitions for indebted that I've seen before include "Owing money, gratitude" , "Owing gratitude to another for help" , "Grateful" , "Under obligation to, for loan or favour" , "Obligated" .)
