Struggle to get iron into thin sheet (5)
I believe the answer is:
wafer
'thin sheet' is the definition.
'wafer' can be an answer for 'sheet' (thesaurus). I'm not certain of the 'thin' bit.
'struggle to get iron' is the wordplay.
'struggle' becomes 'war' (warring is a kind of struggling).
'to get' indicates putting letters inside.
'iron' becomes 'Fe' (Fe is the chemical symbol for iron).
'war' placed around 'fe' is 'WAFER'.
'into' is the link.
Can you help me to learn more?
(Other definitions for wafer that I've seen before include "Ice cream's biscuit" , "Thin, crisp biscuit or bread" , "Light thin biscuit" , "Ice-cream biscuit" , "Very thin slice" .)
