Harrow, I'd think, is more than enough for range (5)
I believe the answer is:
width
'for range' is the definition.
(I've seen this before)
'harrow i'd think is more than enough' is the wordplay.
'WIDTH' is hidden in amongst the letters.
However, I'm unsure how this is indicated.
Can you help me to learn more?
(Other definitions for width that I've seen before include "Breadth" , "Lateral measurement" , "Lateral extent" , "Measurement across" , "Lateral dimension" .)
