Type badly putting an extra t in trivial (5)
I believe the answer is:
petty
'trivial' is the definition.
(I know that trivial can be written as petty)
'type badly putting an extra t' is the wordplay.
I cannot quite understand how this works, but
't' is within the answer.
an anagram of 'type' is 'pety' which is located in the remaining letters.
No letters remain.
This explanation may well be incorrect...
'in' is the link.
Can you help me to learn more?
(Other definitions for petty that I've seen before include "Insignificant and smallminded" , "Inferior" , "Trifling" , "Trivial, piffling" , "Unimportant" .)
