Making an offer to TD in Green struggle (9)

I believe the answer is:

tendering

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

'making an offer' is the definition.
Although both the answer and definition are present participle verbs, I don't see how they can define each other.

'td in green struggle' is the wordplay.
'struggle' is an anagram indicator (I've seen 'struggles' mean this).
'td'+'in'+'green'='tdingreen'
'tdingreen' with letters rearranged gives 'TENDERING'.

'to' is the link.

Can you help me to learn more?

(Another definition for tendering that I've seen is " Offering".)

I've seen this clue in the Irish Times.
