Final answer:
A polite way to describe someone as being short is to use euphemisms like 'vertically challenged' or 'petite'. These provide a respectful and less direct way to refer to someone's stature.
Step-by-step explanation:
A polite euphemism for being short is to say someone is vertically challenged or that they have a petite stature. Euphemisms are a way to express something in a more delicate or less direct manner. For example, instead of saying someone is short, you might say that they are not tall or have a compact build. These phrases aim to convey the same meaning without potentially offending someone about their height.
