After showing that tea can be made in different ways (5)
I believe the answer is:
later
'after showing that' is the definition.
'later' can be an answer for 'after' (I've seen this before). I am unsure of the rest of the definition.
'tea can be made in different ways' is the wordplay.
'can be' is an anagram indicator.
'made in' indicates putting letters inside.
'different ways' becomes 'lr' (I can't justify this - if you can you should believe this answer much more).
'tea' with letters rearranged gives 'ate'.
'ate' placed inside 'lr' is 'LATER'.
Can you help me to learn more?
(Other definitions for later that I've seen before include "At a time in the future" , "Alert (anag.)" , "Following" , "At some time afterwards" , "more modern" .)
