Take out line for slow speech (5)
I believe the answer is:
drawl
'slow speech' is the definition.
(drawl means a slow or lazy style of speech)
'take out line' is the wordplay.
'take out' becomes 'draw' (synonyms).
'line' becomes 'l' (used when specifying particular lines from a poem).
'draw'+'l'='DRAWL'
'for' is the link.
(Other definitions for drawl that I've seen before include "Way of speaking slowly" , "Speak slowly with long vowels sounds" , "Speak lazily with long vowel sounds" , "Slow speech pattern" , "Jimmy Stewart spoke with one" .)
