Wait a minute; the tea is brewing (8)
I believe the answer is:
hesitate
'wait a minute' is the definition.
'hesitate' can be an answer for 'wait' (thesaurus). I'm unsure of the 'a minute' bit.
'the tea is brewing' is the wordplay.
'brewing' indicates an anagram.
'the'+'tea'+'is'='theteais'
'theteais' anagrammed gives 'HESITATE'.
Can you help me to learn more?
(Other definitions for hesitate that I've seen before include "Falter, waver" , "Pause, waver" , "Delay making a decision" , "Stall" , "Show reluctance" .)
