'allowed' is the definition.
The answer and definition are different parts of speech. However, past participle verbs and adjectives occasionally mean the same thing.

'bad similes to be rewritten' is the wordplay.
'to be rewritten' indicates anagramming the letters (I've seen 'being rewritten' mean this).
'bad'+'similes'='badsimiles'
'badsimiles' anagrammed gives 'ADMISSIBLE'.
