Sarnies organised with minimum of fuss, type without decoration (8)
I believe the answer is:
sanserif
'type without decoration' is the definition.
I don't know anything about this answer so I can't judge whether this works.
'sarnies organised with minimum of fuss' is the wordplay.
'organised with' indicates anagramming the letters.
'minimum of' indicates taking the first letters.
The initial letter of 'fuss' is 'f'.
'sarnies' mixed up with 'f' gives 'SANSERIF'.
Can you help me to learn more?
(Other definitions for sanserif that I've seen before include "Like the simplest type" , "font" , "Printing type style" , "Fairness (anag) - printing type" , "Type without projection on letters" .)
