Head of Romans seized by military unit -- held in this? (3-4)
I believe the answer is:
leg-iron
'this?' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.
'head of romans seized by military unit' is the wordplay.
'head of' suggests taking the first letters.
'seized by' means one lot of letters goes inside another.
'military unit' becomes 'legion' (legion is a kind of military unit).
The initial letter of 'romans' is 'r'.
'r' going into 'legion' is 'LEG-IRON'.
'held in' is the link.
Can you help me to learn more?
(Other definitions for leg-iron that I've seen before include "Fetter" , "Ankle restraint for a prisoner" .)
