You and I occupying home most recently built? (6)

I believe the answer is:
newest
'most recently built?' is the definition.
The answer and definition are different parts of speech. However, past participle verbs and adjectives can occasionally mean the same thing.
'you and i occupying home' is the wordplay.
'you and i' becomes 'we' (we means you and I).
'occupying' is an insertion indicator (inserted letters occupy or enter the word).
'home' becomes 'nest' (a bird's home).
'we' going within 'nest' is 'NEWEST'.
Can you help me to learn more?
(Other definitions for newest that I've seen before include "Superlatively modern" , "Most recent or most fashionable" , "Most pristine or latest" , "Freshest, most modern" , "Freshest, most recent" .)
