Coverage of seed trial, part one? (5)
I believe the answer is:
testa
'coverage of seed trial part one?' is the definition.
I can't tell whether this definition defines the answer.
'coverage of seed trial part one?' is the wordplay.
'coverage of' indicates putting letters inside.
'seed trial' becomes 'st' (this might be a standard abbreviation which I don't know about).
'part' becomes 'te' (te is a kind of part).
'one?' becomes 'a'.
'te'+'a'='tea'
'st' going within 'tea' is 'TESTA'.
Can you help me to learn more?
(Other definitions for testa that I've seen before include "cover for a seed" , "Botanical term" , "Seed-coat" , "Protective covering" , "Hard shell" .)
