Unsteady staging area gets removed where river falls (7)
I believe the answer is:
niagara
'river falls' is the definition.
'niagara' can be an answer for 'falls' (Niagara Falls). I am not certain of the 'river' bit.
'unsteady staging area gets removed' is the wordplay.
'unsteady' is an anagram indicator.
'removed' suggests deleting specific letters.
'staging'+'area'='stagingarea'
'stagingarea' with 'gets' taken away is 'aingara'.
'aingara' with letters rearranged gives 'NIAGARA'.
'where' acts as a link.
Can you help me to learn more?
(Other definitions for niagara that I've seen before include "Waterfall at Iran aga" , "Horseshoe, American and Bridal Veil Falls, collectively" , "North American river with famous falls" , "Famous Falls once walked by Blondin" , "N American river and Falls" .)
