Very delicate insect wings I am studying primarily (6)
I believe the answer is:
flimsy
'very delicate' is the definition.
'flimsy' can be an answer for 'delicate' (thesaurus). I am not sure about the 'very' bit.
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for flimsy that I've seen before include "Not strong" , "Insubstantial, light and thin" , "Light and thin, fragile" , "Weak, insubstantial" , "Fragile, of loose structure" .)
