Having only a basic grasp of the Greek alphabet (as used in math and physics mostly), I am sometimes confused when looking at Greek spelling of certain proper names or words. The most common source of this confusion for me is the weird relationship between the letters ν and γ. It seems to me that in some contexts γ is read as if it were ν and I'm curious to know why. Below are the two examples that caught my attention recently:
φεγγάρι(transliterated asfengari) - the word for moonΠλαγκταί(transliterated asPlanktai) - name of the Wandering Rocks from Homer's Odyssey
In both these cases we have a gamma apparently serving as a nu. I was even suspecting the existence of some other forms of certain letters (a'la final forms in Hebrew), but I used Emacs (amateur linguist's best friend) to confirm that those were ordinary gammas.
