Learn Finnish: Etkö tiennyt tiedekunnan myöntäneen stipendin? - Didn't you know that the faculty had granted the scholarship?

This is the past active referative construction (partisiippirakenne), which translates to "that the faculty had granted". It replaces a regular subordinate clause like että tiedekunta oli myöntänyt. In this structure, the subject of the action (tiedekunta) is put into the genitive case (tiedekunnan), and the verb becomes the past active participle ending in -neen.

How exactly do we get the form myöntäneen from the verb myöntää?

First, you find the standard past active participle (often called the NUT-participle), which is myöntänyt (granted). To use it in this specific "that" construction, you need its genitive stem. For these participles, the stem ends in -nee-, and you add the genitive -n to the end, resulting in myöntäneen.

Why is stipendi (scholarship) in the genitive-looking accusative form stipendin?

It is the direct object of the action myöntää (to grant). Normal object rules still apply inside a participle construction! Because the granting of the scholarship was a complete action, the object takes the total object form, which looks exactly like the genitive (stipendin).
