Spear featuring in Anglo-Saxon epic given to Icelandic leader (7)
I believe the answer is:
assagai
'spear' is the definition.
(assagai is a kind of spear)
'anglo-saxon epic given to icelandic leader' is the wordplay.
'anglo saxon' becomes 'as' (this could be a standard abbreviation I've not previously seen).
'epic' becomes 'saga' (I've seen this before).
'given to' means one lot of letters go next to another.
'leader' indicates taking the first letters.
The first letter of 'icelandic' is 'i'.
'as'+'saga'+'i'='ASSAGAI'
'featuring in' acts as a link.
Can you help me to learn more?
(Other definitions for assagai that I've seen before include "Zulu weaponry" , "Spear used in S Africa" , "Weapon" .)
