Is a top from Lidl keeping cycling old lady at a constant temperature? (10)
I believe the answer is:
isothermal
'at a constant temperature?' is the definition.
I can't judge whether this defines the answer.
'is a top from lidl keeping cycling old lady' is the wordplay.
'a top from' indicates taking the first letters.
'keeping' indicates putting letters inside (some letters kept inside).
'cycling' becomes 'other' (I can't justify this - if you can you should believe this answer much more).
'old lady' becomes 'ma' (both can informally mean mother).
The initial letter of 'lidl' is 'l'.
'is'+'l'='isl'
'other'+'ma'='otherma'
'isl' placed around 'otherma' is 'ISOTHERMAL'.
Can you help me to learn more?
(Other definitions for isothermal that I've seen before include "without change in temperature?" , "at constant temperature" .)
