Tongue lifted home-made meal (7)
I believe the answer is:
yiddish
'tongue' is the definition.
(Yiddish is an example)
'lifted home-made meal' is the wordplay.
'lifted' is a reversal indicator (going up in down clue).
'home made' becomes 'diy' (I can't explain this - if you can you should believe this answer much more).
'meal' becomes 'dish' (a dish is a particular meal).
'diy' reversed gives 'yid'.
'yid'+'dish'='YIDDISH'
Can you help me to learn more?
(Other definitions for yiddish that I've seen before include "Old Jewish language" , "Mixed language used by Jews of central and eastern Europe" , "Jewish tongue" , "German dialect widely used by European Jews before the Holocaust" , "European Jews' vernacular" .)
