Spread out blind to get through (6)
I believe the answer is:
effuse
'spread out' is the definition.
(effuse can mean to emit or spread)
'blind to get through' is the wordplay.
'blind' becomes 'eff' (to 'eff and blind' can informally mean to swear).
'to get through' becomes 'use' (get through can mean to gradually use something up).
'eff'+'use'='EFFUSE'
(Other definitions for effuse that I've seen before include "Gush" , "Pour or spread out" , "Pour forth (words)" .)
