If you've noticed that your car has thick smoke coming out of the exhaust pipe, it may be a sign that your engine needs some attention. Just like you can examine an animal's stool to get an idea of its health, you can pay attention to the quality of your car's exhaust to get an idea of what's going on inside the engine.

First attested in English late fourteenth century, the word coriander derives from the Old French: coriandre, which comes from Latin: coriandrum, in turn from Ancient Greek: ÎºÎ¿ÏÎ¯Î±Î½Î½Î¿Î½ koriannon.
