Where Davy Crockett fell - for a Los Angeles doctor? (5)
I believe the answer is:
alamo
'where davy crockett fell' is the definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
'a los angeles doctor?' is the wordplay.
'los angeles' becomes 'LA' (abbreviation).
'doctor?' becomes 'mo' (medical officer).
'a'+'la'+'mo'='ALAMO'
'for' acts as a link.
Can you help me to learn more?
(Other definitions for alamo that I've seen before include "Famous battle in Texas launched by the Mexican army" , "Texan battle" , "national monument" , "Texas fort, scene of famous siege by Mexican army" , "Mexicans invested in Texas" .)
