I am an English student from Austria and have a question concerning morphology.
In the reading I did for one of my introductory courses on linguistics there was a chapter on the analysis of word-formation and which affixes get attached to the word first (in Plag et al. 2009). He explained it quite well that one should have a look at the meaning of the word to discern of how many components it consists. His example was 'unfearful' and it was easy to understand why fearful was formed first, after which the prefix un- can be added.
So, now I ask, what happens if you have a word like 'unhappier' which in my analysis consists of the adjective happy, a suffix for the comparative and a prefix for the negation. Is there any way to analyse whether unhappy or happier was formed first? Or is this a stupid question, because the comparative does not create a now word per se, rather changes it's grammatical function?
