Has she no right to enter the water? (6)

I believe the answer is:
senora
'has she' is the definition.
The definition suggests a singular noun which matches the answer.
'no right to enter the water?' is the wordplay.
'right' becomes 'r' (common abbreviation).
'to enter' is an insertion indicator.
'the water?' becomes 'sea' (the sea is water).
'no'+'r'='nor'
'nor' put within 'sea' is 'SENORA'.
Can you help me to learn more?
(Other definitions for senora that I've seen before include "Spanish title" , "Foreign lady; reason (anag.)" , "Lady of Spain" , "Mrs or madam (Spanish)" , "Lady overseas" .)
