Offering to be there (7)
I believe the answer is:
present
This might be a double definition.
'offering' is the first definition.
(I've seen this before)
'be there' is the second definition.
'present' can be an answer for 'be' (presenting is a kind of being). I'm not certain of the 'there' bit.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for present that I've seen before include "Hand over < donation" , "host" , "Give - what's received at Christmas?" , "Serpent (anag.)" , "Introduce < and compere < tense" .)
