Brain Teaser Of The Day: One Letter Changed

In this brain teaser you have been given two definitions. Each pair of definitions is for two unrelated words. Your task is to discover what these two words are. In the answer to the second word, I took the first word, but changed one of its letters to make a completely different word. (i.e. table – fable)

1. An instrument used to measure time – an outer garment.
2. An instrument used in woodworking for smoothing wood – a shallow dish used for eating food.
3. A deep basin used to hold liquids or food – to utter a loud prolonged cry.
4. A position of authority – a group of singers.
