What' the difference between "motorcar" and "motorcycle"? In English-Chinese Dictionary, They are meaning： motorcar 汽车 motor-car 摩拖车 motor car 汽车 motorcycle 摩托车 -------- "汽车" means "car" "摩托车" means "motorcycle" ---------------- But in Chinese,“汽车" is different to "摩托车". So, Could it be that motor car = motorcar ≠ motor-car？ motor car = motorcar “≠” motor-car？Yes, so that it is right? motor car: 4 wheels motorcar: 4 wheels motor-car: 2 wheels I have been thinking they are the same word before.
