Here in France, caught the French descendants in cold weather? (7)
I believe the answer is:
icicles
'descendants in cold weather?' is the definition.
Although both the answer and definition are plural nouns, I can't see how they can define each other.
'here in france caught the french' is the wordplay.
'here in france' becomes 'ici' ('here' in French).
'caught' becomes 'c' (cricket abbreviation).
'the french' becomes 'les' (les is the in french).
'ici'+'c'+'les'='ICICLES'
Can you help me to learn more?
(Other definitions for icicles that I've seen before include "Frozen pendants" , "Frozen drips" , "'When ... hang by the wall / And Dick the shepherd blows his nail' (Shakespeare)" , "They hang by the wall (L.L.Lost)" , "Pendent spears of frozen water (7)" .)
