'proved useful for ages' is the definition.
The answer and definition are not the same part of speech. However, past participle verbs and adjectives can occasionally mean the same thing.

'freely admit a dumped settee' is the wordplay.
'freely' indicates anagramming the letters.
'dumped' suggests deleting specific letters.
'admit' with 'a' removed is 'dmit'.
'dmit'+'settee'='dmitsettee'
'dmitsettee' anagrammed gives 'TIME-TESTED'.
