Perhaps cure is close for researcher probing lost diary (3-3)
I believe the answer is:
air-dry
'perhaps cure' is the definition.
'air-dry' can be an answer for 'cure' (thesaurus). I'm unsure of the 'perhaps' bit.
'close for researcher probing lost diary' is the wordplay.
'close for' suggests the final letters (the letter which closes the word).
'probing' is an insertion indicator (probe can mean to make a hole in).
'lost' is an anagram indicator.
The final letter of 'researcher' is 'r'.
'diary' is an anagram of 'airdy'.
'r' going into 'airdy' is 'AIR-DRY'.
'is' is the link.
Can you help me to learn more?
(Other definitions for air-dry that I've seen before include "Remove moisture by atmospheric contact" , "Remove moisture by exposure" .)
