for the first word
find a verb in the category: four letter word, second letter = "u"
make sure it's in (non-3.sing) present tense
make sure it doesn't end in "e"
add "-ing" to the end
i think
there are a few three-letter words too (hum -> humming)
and five letter? i came up with one earlier but i can't recall it atm
without any context there isn't any one correct answer and there are also some answers that arent verbs.
in this case it functions as an adjective anyway
