Inclined to speak fast (5)
I believe the answer is:
leant
'inclined' is the definition.
(I've seen this in another clue)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for leant that I've seen before include "Tilted" , "Slanted" , "Relied (on); inclined" , "Inclined (towards)" , "pressed on" .)
