Some land in Lesotho for domestic protectors (5)
I believe the answer is:
lares
'domestic protectors' is the definition.
The definition suggests a plural noun which matches the answer.
'some land in lesotho' is the wordplay.
'some land' becomes 'are' (historical unit of measurement - l00 square metres).
'in' is an insertion indicator.
'lesotho' becomes 'ls' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'are' placed into 'ls' is 'LARES'.
'for' is the link.
Can you help me to learn more?
(Other definitions for lares that I've seen before include "Veteran retreats" , "Roman household gods" .)
