Latin derivatives

[kaaskala]

My work is all about the structure and meaning of derivative adjectives. And it was quite easy with flower-flowered pairs. But what about such words as "final" or "annual"? Their stems "ann" and "fin" do not exist separately in English but still they are called derivatives. Should I analyse them like other adjectives with affixes or treat them like borrowings or simple words?
Please help

It rather depends on the approach you choose to take. Ultimately you can trace the origin of your words back to the Latin words finalis/finis and annualis/annalis/annus. However, in English itself, there are no independent words fin (in this meaning) or ann/enn. Actually, I don't see final as a problem, because the -al is part of the original stem.
I suppose that one way would be to propose a class of 'theoretical anglicised Latin stems', which would include such stems as ann/enn, circum, phon, etc.
