Here are some examples in Czech:
1. kořen (
kořeny pl.): in the plural form refers to family origins, similarly to English.
Kořen is also the basic part of a word that doesn't change.
2. kmen: a tribe, also a level of classification in biology (equivalent to phylum) and part of a word that includes
kořen.
3. větev: sometimes refers to a field of study/specialisation within a school (
humanitní větev), also used in genealogy (similar to bloodline, I believe).
4. list: a sheet of paper and an outdated word for letter - the postman used to be called
listonoš (literally the leaf-carrier).
5. květ: -
6. koruna: the thing the king has on his head, the Czech currency (also used in Scandinavian countries),
Koruna Česká refers to the Czech lands in the medieval and early modern periods
,
korunka (diminutive) in dentistry is an artificial part of a tooth that sits on what's left of your original tooth. There's also an idiom:
nasadit něčemu korunu (to put a crown onto something): usually sarcastic, to say you were already doing something stupid and embarrassing yourself in the process and then you did one last thing, taking the embarrassment to another level.
I think many of these also apply to English. Please share your words and meanings, it doesn't matter if no one here is learning your language and you don't have to be a linguist. Just share whatever you can think of.
