Key lingo one put in French person’s mouth? (8)
I believe the answer is:
escargot
'one put in french person's mouth?' is the definition.
I can't judge whether this definition defines the answer.
'key lingo' is the wordplay.
'key' becomes 'esc' ('Escape' key on a computer keyboard).
'lingo' becomes 'argot' (synonyms).
'esc'+'argot'='ESCARGOT'
Can you help me to learn more?
(Other definitions for escargot that I've seen before include "One continually moving house" , "French food" , "Hardly fast food" , "Edible snail (from Fr.)" , "Got scare from edible French snail" .)
