Nut, a large Scottish man, died (6)
I believe the answer is:
almond
'nut' is the definition.
(I know that almond is a type of edible nut)
'a large scottish man died' is the wordplay.
'large' becomes 'L' (eg in clothes sizes).
'scottish man' becomes 'mon' (I am not sure about this - if you are sure you should believe this answer much more).
'died' becomes 'd' (abbreviation next to the year of someone's death).
'a'+'l'+'mon'+'d'='ALMOND'
Can you help me to learn more?
(Other definitions for almond that I've seen before include "Fruit kernel of a peach-related tree" , "Kind of nut, makes nice icing on cake" , "Oval-shaped nut" , "Oval-shaped edible seed" , "Old man with nice nut" .)
