Famous name for a dog, that is (5)
I believe the answer is:
curie
'famous name' is the definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
'a dog that is' is the wordplay.
'a dog' becomes 'cur' (both can mean a despicable person).
'that is' becomes 'ie' (short for Latin 'id est', 'that is').
'cur'+'ie'='CURIE'
'for' acts as a link.
Can you help me to learn more?
(Other definitions for curie that I've seen before include "Nobel Prize winner for physics (1903) and chemistry (1911), d. 1934" , "measure of radioactivity" , "Pioneer in radioactivity" , "Unit of radioactivity" , "Marie ---, found radium" .)
