Defective vehicle? (5)
I believe the answer is:
buggy
This might be a double definition.
'defective' is the first definition.
Both the definition and answer are adjectives. Perhaps they are linked in a way I don't understand?
'vehicle?' is the second definition.
(buggy is a kind of vehicle)
Can you help me to learn more?
(Other definitions for buggy that I've seen before include "Vehicle for baby, golfer or moon explorer" , "Small open motor vehicle; infested" , "A small vehicle as for baby" , "Pushchair - small motorised vehicle" , "Of software, containing errors" .)
