Deprived of nationality? It’s not verbally declared (8)

I believe the answer is:
unstated
'deprived of nationality?' is the definition.
The answer and definition are not the same part of speech. However, adjectives and past participle verbs sometimes define each other.
'not verbally declared' is the wordplay.
'not' becomes 'un' (prefix meaning 'not').
'verbally declared' becomes 'stated' (synonyms. I am not sure about the 'verbally' bit.).
'un'+'stated'='UNSTATED'
'it's' is the link.
Can you help me to learn more?
(Other definitions for unstated that I've seen before include "Not said" , "taken for granted" , "kept silent" , "Not declared" , "not mentioned" .)
