I've been working thru the lessons, & have taken some time out to ensure that I really know the vocab up thru Lesson XII completely. It's been helpful for me, in learning verbs' principal parts, to understand the patterns of sound changes. I know that some verbs will just be irregular, & that we might not be able to identify them as part of any pattern. But to the extent that this pattern-finding is possible, I'm trying to do it.
So, I'm stumped with ἀνάσσω, ἁνδάνω, ἔιρω, & φέρω.
I see that ἀνάσσω comes from ϝανακ-, so it makes sense that the future would be ἀνἀξω & the aorist ἤναξα. But why does the κ become σσ in the present? Does that pattern happen anywhere else in Homeric Greek?
With ἁνδάνω, the other forms drop the ν. Or the present adds it. Where does the ν go, or where does it come from?
What's with the π in the aorist of ἔιρω?
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?
Thanks for any help!
