Hypocrite pairs off outside hotel on the borders of Europe (8)
I believe the answer is:
pharisee
'hypocrite' is the definition.
(I've seen this before)
'pairs off outside hotel on the borders of europe' is the subsidiary indication.
'off' indicates anagramming the letters.
'outside' is an insertion indicator.
'hotel' becomes 'h' (phonetic alphabet: alpha, bravo, charlie etc.).
'on' means one lot of letters go next to another.
'the borders of' says to hollow out the word (remove centre letters).
'europe' with its middle removed is 'ee'.
'pairs' with letters rearranged gives 'paris'.
'paris' placed around 'h' is 'pharis'.
'pharis'+'ee'='pharisee'
(Other definitions for pharisee that I've seen before include "Sanctimonious hypocrite" , "Strict Jew (hist.); hypocrite" , "hypocritical type" , "Ancient Jewish sectarian" , "scribe's partner" .)
