In case you don't know, one of the most common ways of forming the present stem historically was adding -y- and then the -y- had various effects on the previous consonant, and in this case κy > σσ (Attic ττ) is a well-established sound change. It also occurs in verbs like φυλάσσω or κηρύσσω.
With ἁνδάνω, the other forms drop the ν. Or the present adds it. Where does the ν go, or where does it come from?
I'm not sure which ν you mean, but there both odd. Basically another common way to form the present stem was to infix an -ν- inside the root, but this verb also shows the additional suffix -αν- in the present. This combination is also pretty common:
μανθάνω < aorist stem μαθ-
λαμβάνω < λαβ-
λανθάνω < λαθ-
πυνθάνομαι < πυθ-
What's with the π in the aorist of ἔιρω?
These just go back to different roots, I don't think there's any connection.
The various forms of φέρω seem to have absolutely nothing to do with one another. Is that correct? Do they come from different Proto-Indo-European roots?
That's right -- these are different roots as well.
If you haven't seen it, there's a book by Sihler on Greek and Latin that I think you'll find very interesting if you want know about these sorts of questions.
