Measures for certain areas (5)
I believe the answer is:
yards
This clue could be a double definition.
'measures' is the first definition.
(yard is a kind of measure)
'certain areas' is the second definition.
'yards' can be an answer for 'areas' (yard is a kind of area). I'm not sure about the 'certain' bit.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for yards that I've seen before include "Three feet in each" , "Enclosed paved areas behind buildings" , "Pieces of uncultivated ground adjoining buildings" , "belonging to investigators" , "Short distance" .)
