Was inclined to have a spare tea (5)
I believe the answer is:
leant
'was inclined' is the definition.
(I've seen this in another clue)
'a spare tea' is the wordplay.
'a spare' becomes 'lean' (I've seen this before).
'tea' becomes 't' (I've seen this in other clues).
'lean'+'t'='LEANT'
'to have' acts as a link.
(Other definitions for leant that I've seen before include "bent over" , "Tipped" , "Relied (on); inclined" , "Tilted" , "Rested sideways (on something)" .)
