Years ago, I was baffled by the phrases the native speakers often use that I had never learned at all from textbooks or classes or any of my readings. When it is a cold weather, people often say “nippy”; when something is not affordable, people don’t say expensive but rather use the word “steep”; when they want to have a cup of tea, they don’t say “brew” but rather “steep”. And so far I’ve never heard anybody use the word “careless” as if it is only there to decorate the dictionary–the word “sloppy” is usually used in its place. And the phrase “bad tempered” is rarely used. People will say “he has a temper” to represent a bad temper, or use “grumpy” or “sulky”.
The following are some commonly used words starting with “s” and ending with “p” or “py”

stump: (noun) the part of something (as a tooth or a pencil) that remains after the rest has been removed. Used as a verb, stump can mean different things. The most common use of stump is when someone — like a teacher — asks a question that no one can answer. That’s a case of the teacher stumping the class. Also, politicians traveling through a district, making speeches are stumping, giving what are called stump speeches.
