Able to bend, one held in place (6)
I believe the answer is:
suited
'able' is the definition.
(thesaurus)
'bend one held in place' is the wordplay.
'bend' becomes 'u' (a U-bend is a kind of bend - pipe under sink).
'one' becomes 'i' (roman numeral).
'held in' means one lot of letters goes inside another.
'place' becomes 'sted' (I have seen 'Old place' mean 'sted' so perhaps 'place' could also mean 'sted').
'u'+'i'='ui'
'ui' inserted within 'sted' is 'SUITED'.
'to' acts as a link.
(Other definitions for suited that I've seen before include "Well adapted" , "agreed" , "Appropriate, fitting" , "Matched" , "Befitted" .)
