Hurry to protect one manuscript likely to fall apart (6)
I believe the answer is:
flimsy
'likely to fall apart' is the definition.
I can't judge whether this definition defines the answer.
'hurry to protect one manuscript' is the wordplay.
'hurry' becomes 'fly' (I've seen this before).
'to protect' indicates putting letters inside (inserted letters are protected or taken in).
'one' becomes 'i' (Roman numeral).
'manuscript' becomes 'ms' (abbreviation for manuscript).
'i'+'ms'='ims'
'fly' placed around 'ims' is 'FLIMSY'.
Can you help me to learn more?
(Other definitions for flimsy that I've seen before include "Lightweight" , "Lacking strength and solidity" , "Not strong" , "Fragile, of loose structure" , "Weak, insubstantial" .)
