Mixing It Up In Polish (Big Time)

I had previously posted this in three parts, but recently decided to consolidate it into one post and add some more words to it, as well as alphabetize the list by the first entry.  I did that because I was having a hard time figuring out whether I had already included words, so alphabetizing them and having them in one list will make it easier to determine whether I have already considered any given words.  From now on I will just add words to this post when I have identified more easily confused words.

When you are learning Polish, there are a whole lot of words that can be easily confused with each other.  For an English speaker, this is compounded because all the words are tongue twisters anyway.  You have no idea how many times I repeated the words "coś zjeść" (something to eat) over and over again before I could finally say them somewhat reliably.

Plus, when you learn new words that are similar to other words you knew, it can suddenly create a minefield of confusion.

Other potentially confusing items:

Phrases with "północ" can be confusing because the word can either mean "north" or "midnight":

na północy – in the north
na północ – to the north
z północy – from the north

o północy – at midnight

"Południe" can mean either "south" or "noon" as well:

na południe – to the south
na południu – in the south
z południa – from the south

po południu – in the afternoon
w południe – at midday

There are also a whole bunch of words that have to do with thinking and/or mental processes that either contain "-myśl" or "-mysł" (where the accented mark switches between the "s" and the "l".  There are just so many that it makes my head swim.

Also I have mixed up a lot of words that start with "przy"- and "prze-".

I'd be interested in hearing what words you have gotten mixed up with other words in any languages you were studying.
