@celrydoor Cool! As soon as read that, I hypothesized that we get Ukrainian ф in borrowings from Greek θ - works for марафон and Афінф.
But I thought that maybe 2 data points is not enough to support a generalization like that.
And then I thought of театр /teatr/ "theatre". So that hypothesis doesn't work.
But I've learned that even discovering a non-pattern can help with the ultimate goal: learning the words.
