Recently I started studying Czech and I learned the word "lék", pill/medicine and "lékař", doctor/physician. In Polish there is a similar one. They bear a superficial resemblance with Swedish "läke" and, since I have not been able to find a slavic etymology, I was wondering if this could be a germanic loanword.
I was guessing that, if this was a relatively recent loanword, it should have been from German to Czech, but, since I do not recall any similar word in German, maybe this could be a very old loanword from Proto-germanic to Proto-slavic, or something of the like?. My only reference is that other languages (like Finnish) indeed borrowed the word for "medicin" from germanic languages (lääke, in modern Finnish)
Also, I would love to know if there is some sort of digitalized database or something of the like where such things can be checked. I have no formation in linguistics and I don't know many resources.
As far as I know, you're correct that there is no cognate in modern standard German.
