aphar

to clean out (English), נָקִי (Hebrew), обчистить (Russian)

these derivatives of the root normally meaning to clean have an informal/vernacular connotation of depriving someone of all their possessions.

PS. TBH, I suspect that the Hebrew reference might not be relevant today...

In quite a few languages these words are related:

In many European languages slave comes from Slav (via Latin).

Славяне были вольнолюбивым народом. Их часто угоняли в рабство, но и там они не работали…

Both English and Russian have just one word for Knowledge: to know/знать. All other terms, like familiarity/знакомство, convey connotations that can also be expressed by the main word, possibly with an adverb.

However, in French and Hebrew, there are two words for knowledge, and the difference between them appears to be identical:

savoir/לָדַעַת

to know something one has learned, and never a human being (outside of the biblical context)

connaître/להכיר

to know about something or someone by having met them

What about other languages?
