Ironic about the tea brewed being so weak (6)
I believe the answer is:
watery
'so weak' is the definition.
'watery' can be an answer for 'weak' (synonyms). I am not certain of the 'so' bit.
'ironic about the tea brewed' is the wordplay.
'ironic' becomes 'wry' (wry can mean ironic or humorous).
'about' is an insertion indicator.
'brewed' is an anagram indicator.
'tea' with letters rearranged gives 'ate'.
'wry' going around 'ate' is 'WATERY'.
'being' is the link.
Can you help me to learn more?
(Other definitions for watery that I've seen before include "Weak, too diluted" , "Overly diluted, thin" , "Insipid" , "Aqueous" , "(Of food) thin, tasteless" .)
