Has it no right to be negative? (3)
I believe the answer is:
nor
'has it no right to be negative?' is the definition.
I know that 'negative' relates to this answer.
'right to be negative?' is the wordplay.
'right' becomes 'r' (common abbreviation).
'to' means one lot of letters go next to another (I've seen this in other clues).
'be negative?' becomes 'no'.
'r' put after 'no' is 'NOR'.
Can you help me to learn more?
(Other definitions for nor that I've seen before include "And not either" , "And not; Norman (abbr.)" , "Conjunction meaning 'and not'" , "Negative word" , "Neither one ... the other" .)
