Learn Finnish: Ketterä koodari keskittyy tuotekehityksen nopeuttamiseen. - The agile coder focuses on speeding up product development.

The verb keskittyä (to focus) requires its target to be in the illative case. When focusing on an activity, Finnish requires the verbal noun form (-minen), which becomes -miseen in the illative. Verbs expressing mental focus, participation, or habituation (like keskittyä, osallistua, or tottua) govern this -miseen form, unlike verbs of movement or starting which take the 3rd infinitive (-maan).

Why is product development translated using the genitive form tuotekehityksen?

Because nopeuttaminen functions grammatically as a noun (the act of speeding up), it cannot take a direct object in the accusative or partitive case like a regular verb. Instead, the object of a verbal noun takes the genitive case. You can think of it as literally meaning the speeding up of product development.

How is the word nopeuttamiseen built from its root?

It starts with the adjective nopea (fast), which becomes the transitive verb nopeuttaa (to speed up). By adding the -minen suffix, it turns into the verbal noun nopeuttaminen (the activity of speeding up). Finally, because the main verb keskittyä requires the illative case, it takes the illative ending to become nopeuttamiseen.
