New sort of tea without added water (4)
I believe the answer is:
neat
'added water' is the definition.
The answer and definition are not the same part of speech. However, past participle verbs and adjectives can occasionally define each other.
'new sort of tea without' is the wordplay.
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'sort of' indicates an anagram.
'without' is an insertion indicator.
'tea' with letters rearranged gives 'eat'.
'n' put into 'eat' is 'NEAT'.
Can you help me to learn more?
(Other definitions for neat that I've seen before include "Steers" , "Tidy and uncluttered" , "efficient" , "Trim - tidy - without water" , "compact" .)
