Henry II touring most of far state (6)
I believe the answer is:
hawaii
'far state' is the definition.
'Hawaii' can be an answer for 'state' (Hawaii is a state of the USA). I'm not sure about the 'far' bit.
'henry ii touring most' is the wordplay.
'henry' becomes 'H' (symbol for the unit of electrical inductance).
'touring' is an insertion indicator (touring can mean going round).
'most' becomes 'awa' (I am not sure about this - if you are sure you should believe this answer much more).
'h'+'ii'='hii'
'hii' going around 'awa' is 'HAWAII'.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for hawaii that I've seen before include "US Pacific island state" , "It became a US territory in 1900" , "State capital is Honolulu" , "Pacific island group" , "USA's 50th state" .)
