Speak volubly in some place out of turn (5)
I believe the answer is:
spout
'speak volubly' is the definition.
'spout' can be an answer for 'speak' (spouting is a kind of speaking). I'm unsure of the 'volubly' bit.
'some place out of turn' is the wordplay.
'some place' becomes 'spot' ('spot' can be a synonym of 'place'**).
'out of' means one lot of letters goes inside another.
'turn' becomes 'u' (a 'U-turn' is a kind of turn).
'spot' enclosing 'u' is 'SPOUT'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for spout that I've seen before include "Pontificate" , "Discharge" , "Mouth of a kettle" , "rant" , "Make speech; part of teapot" .)
