I believe the answer is:

'cloth' is the definition.
(cotton is a kind of cloth)
'frantic otto now provides' is the wordplay.

'COTTON' can be found hidden inside 'frantic otto now'.
(Other definitions for cotton that I've seen before include "Material" , "Cloth made from fine hairs of seed pod" , "Plantation product" , "Fabric woven from plant fibres" , "Fabric made from tropical plant - old man river don't plant it" .)
