Heteronyms are words that are spelled the same but have different pronunciations and meanings.
Here are some examples:
* bow (to bend at the waist) vs. bow (a weapon)
* lead (a heavy metal) vs. lead (to guide)
* minute (a small amount of time) vs. minute (very small)
* tear (a drop of liquid from the eye) vs. tear (to rip)
These words can sometimes be confusing, but they add a fun element of complexity to the English language.
