saat = hour and clock is very fascinating to me...like, in English "the clock strikes twelve" and "I will clock you" are different (it's midnight/noon vs. I will punch you) but at least when both words are "clock" there is a difference (one is a noun and one is a verb). Same with "can"..."I have a can of soup" vs. "can I have some soup". For English speakers out there, do we have 2 identical words that are the same parts of speech but mean 2 different things? I'm sure we do, I just can't think of any examples at the moment.
There are many. Off the top of my head, you have “metre” (a unit of length or the rhythm in poetry or music), “ruler” (a person who rules over something or a measuring implement), “lap” (your thighs when sitting or part of a race), and “pole” (a rod or one of two opposite points)—and this is without getting into homophones and homographs. I think it's a bit rarer with verbs, but there are some examples (e.g., “to beat”: to strike repeatedly or to defeat or to pulsate).
