Invest capital in kitchen equipment (4)
I believe the answer is:
sink
This could be a double definition.
'invest' is the first definition.
(thesaurus)
'capital in kitchen equipment' is the second definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe they are linked in a way I don't understand?
Can you help me to learn more?
(Other definitions for sink that I've seen before include "Washing facility" , "Plummet" , "Invest capital in - kitchen basin - founder" , "Drop beneath the surface" , "Washbasin" .)
