America is backtracking about mistake in Hispanic mountains (6)
I believe the answer is:
sierra
'hispanic mountains' is the definition.
'sierra' can be an answer for 'mountains' (I've seen this before). I'm not certain of the 'hispanic' bit.
'america is backtracking about mistake' is the wordplay.
'america' becomes 'a' (common abbreviation - e.g. in organisation names).
'backtracking' is a reversal indicator.
'about' is an insertion indicator.
'mistake' becomes 'err' (to err is to make a mistake or blunder).
'a'+'is'='ais'
'ais' reversed gives 'sia'.
'sia' placed around 'err' is 'SIERRA'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for sierra that I've seen before include "Model of car from Ford" , "Spanish range of mountains" , "Mountain range -- code word for S" , "One range" , "Long range" .)
