 If the "-е-" of the past passive participle is stressed then the "е" will mutate into an "і".Examples include "питання" from "питати" and "носіння" from "носити".Note that any Class 3 verbs in -увати or -ювати will restore the "у" or "ю" малювання from мальований (малювати)

The verbal noun in Ukrainian is derived from the Common Slavic verbal noun, where it was formed by adding "*-ĭjе" to the past passive participle without the "*ŭ" ending.
