Bride aged badly, hiding old age in a good way (10)

I believe the answer is:

biodegrade

I'm a little stuck... Click here to teach me more about this clue!

'age in a good way' is the definition.
The definition suggests a verb in its base form which matches the answer.

'bride aged badly hiding old' is the wordplay.
'badly' is an anagram indicator.
'hiding' indicates putting letters inside.
'old' becomes 'o' (abbreviation).
'bride'+'aged'='brideaged'
'brideaged' anagrammed gives 'bidegrade'.
'bidegrade' going around 'o' is 'BIODEGRADE'.

Can you help me to learn more?

(Another definition for biodegrade that I've seen is " Rot!".)

I've seen this clue in The Independent.
