I found this headline:
Kolmas myrsky uhkaa Suomea.....since newspaper headlines are about sensationalism, it didn't take long to figure out what, uhkaa meant....though it wasn't exactly easy....
I know about the disappearing "k" with consonant gradation....but what clues would a native speaker see in this word, uhkaa, that would lead to the verb infinitive taking the form...uhata??....
I suspect the main clues are the double "a" and the single "k"....but, then, there is the verb, hohkata, which superficially looks similar, but does not seem to attract consonant gradation in any of its forms....why would it not take a verb infinitive, *hohata.....
