Word structure
The word is made up of the negating prefix 'Un-' and the noun 'das Vermögen' (here in the sense of ability, capacity). 'Unvermögen' (inability) therefore literally means 'non-ability'.
EXAMPLE

Sentence structure with infinitive
'Unvermögen' (inability) is very often expanded with a 'zu' + infinitive construction to specify what someone cannot do. The structure is: 'das Unvermögen, etwas zu tun' (the inability to do something).
EXAMPLE

She was annoyed by her inability to say no.

Use with nouns
