'strong' is the definition.
(I've seen this before)

'nevertheless twisted out of line' is the wordplay.
'nevertheless twisted out of' becomes 'wi' (I can't justify this - if you can you should give a lot more credence to this answer).
'line' becomes 'ry' (abbreviation for railway).
'wi'+'ry'='WIRY'
