One holds hands eventually with model (5)

I believe the answer is:

ideal

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

'model' is the definition.
(ideal can mean model or perfect)

'one holds hands eventually' is the wordplay.
'one' becomes 'i' (Roman numeral).
'holds hands eventually' becomes 'deal' (I can't explain this - if you can you should believe this answer much more).
'i'+'deal'='IDEAL'

'with' is the link.

Can you help me to learn more?

(Other definitions for ideal that I've seen before include "highly desirable" , "In her dreams" , "faultless" , "Best possible" , "principle to be aimed at" .)
