Group meeting cross, upset by European getting lavish praise (5)
I believe the answer is:
extol
'lavish praise' is the definition.
'extol' can be an answer for 'praise' (I've seen this before). I'm unsure of the 'lavish' bit.
'group meeting cross upset by european' is the wordplay.
'group meeting' becomes 'lot' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'cross' becomes 'x' (X is cross-shaped).
'upset' shows that the letters should be reversed in order.
'by' says to put letters next to each other.
'european' becomes 'E' (abbreviation e.g. EU).
'lot'+'x'='lotx'
'lotx' written backwards gives 'xtol'.
'xtol' after 'e' is 'EXTOL'.
'getting' acts as a link.
Can you help me to learn more?
(Other definitions for extol that I've seen before include "be lavish with praise" , "Praise highly, laud" , "Lift up" , "Praise enthusiastically" , "celebrate" .)
