Can husband start travelling without a helmet? (3,3)
I believe the answer is:
tin hat
'helmet?' is the definition.
(tin hat is a kind of helmet)
'can husband start travelling without a' is the wordplay.
'can' becomes 'tin' (synonyms).
'husband' becomes 'h'.
'start travelling' becomes 't' (I am not sure about this - if you are sure you should believe this answer much more).
'without' means one lot of letters goes inside another ('without' can be similar in meaning to 'outside').
'h'+'t'='ht'
'ht' placed around 'a' is 'hat'.
'tin'+'hat'='TIN HAT'
Can you help me to learn more?
(Other definitions for tin hat that I've seen before include "Steel helmet (informal)" , "Headgear, worn for protection" , "Protective helmet once worn by constuction and mine workers" , "Finish it off to put the protective headgear on it" , "Soldier's helmet" .)
