After reflection, nothing brought to attention in row (6)
I believe the answer is:
linear
'after reflection nothing brought to attention in row' is the definition.
I can't judge whether this definition defines the answer.
'after reflection nothing brought to attention' is the wordplay.
'after reflection' shows that the letters should be reversed in order.
'nothing' becomes 'nil' (eg nil is zero in football).
'brought to' says to put letters next to each other.
'attention' becomes 'ear' (having someone's ear is having their attention).
'nil' reversed gives 'lin'.
'lin'+'ear'='LINEAR'
Can you help me to learn more?
(Other definitions for linear that I've seen before include "Consisting of lines" , "adopting common narrative style" , "One-dimensional" , "Long and narrow, of one dimension" , "following straight path" .)
