Weird feeling taking English couple around Ireland by ship (8)
I believe the answer is:
eeriness
'weird feeling' is the definition.
'english couple around ireland by ship' is the wordplay.
'english' becomes 'e' (abbreviation).
'couple' shows that letters should be duplicated.
'around' means one lot of letters goes inside another.
'ireland' becomes 'erin'.
'by ship' becomes 'ss' (I am not sure about the 'by' bit.**).
'e' duplicated is 'ee'.
'ee' placed around 'erin' is 'eerine'.
'eerine'+'ss'='EERINESS'
'taking' acts as a link.
(Other definitions for eeriness that I've seen before include "Horror movie featuring such" , "'Weirdness, scariness (8)'" , "Ghostly quality" , "'Ghostliness, scariness (8)'" , "Is serene (anag.)" .)
