Tell in Scots island about the missing husband (7)
I believe the answer is:
narrate
'tell' is the definition.
(I know that tell can be written as narrate)
'scots island about the missing husband' is the wordplay.
'scots island' becomes 'arran' (Isle of Arran in Scotland. I am not sure about the 'scots' bit.).
'about' shows that the letters should be reversed in order.
'missing' suggests deleting specific letters.
'husband' becomes 'h'.
'arran' back-to-front is 'narra'.
'the' with 'h' taken away is 'te'.
'narra'+'te'='NARRATE'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for narrate that I've seen before include "Relate, recount" , "Relay" , "Chronicle" , "'Recount, tell (7)'" , "Rare ant (anag.)" .)
