Explorer just stopping short, interrupted by porter? (7)
I believe the answer is:
raleigh
'explorer' is the definition.
(I've seen this before)
'just stopping short interrupted by porter?' is the wordplay.
'just' becomes 'right' ('right' can be similar in meaning to 'just').
'stopping short' means to remove the last letter.
'interrupted by' means one lot of letters goes inside another.
'porter?' becomes 'ale' (porter is a kind of ale).
'right' with its last letter taken away is 'righ'.
'righ' enclosing 'ale' is 'RALEIGH'.
(Other definitions for raleigh that I've seen before include "Elizabethan explorer" , "SECOND PART OF 12 ACROSS" , "Tudor explorer" , "Queen's favourite" , "English navigator executed for treason in 1618" .)
