A slope that’s slippery in US city (2,4)
I believe the answer is:
el paso
'us city' is the definition.
(city in Texas)
'a slope thataeurtms slippery' is the wordplay.
'a slope' anagrams to 'EL PASO'.
But, I am unsure how the anagram is indicated.
'in' is the link.
Can you help me to learn more?
(Other definitions for el paso that I've seen before include "city on Mexican border" , "West Texas town" , "City of Texas on the Rio Grande; aslope (anag.)" , "US city" , "Texan city" .)
