Behold, the day of the LORD cometh, Cruel, and full of wrath and fierce anger; To make the earth a desolation, And to destroy the sinners thereof out of it,
Rashi on Isaiah

Ibn Ezra on Isaiah
אכזרי Cruel. The י is paragogic, as in 10The י in פנימי is not of the same kind as that in אכזרי, as stated by I. E. himself (Moznaim, On the Hirek); in his commentary on Lev. 16:21, he quotes פנימי as an instance of an adjective with יו״ד להתיחס, a formative י to indicate relation. In his Safah Berurah (p. 29), however, he quotes פנימי and אכזרי as two instances of the paragogic יו״ד נוסף) י). This discrepancy seems to have its origin in the use of the word נוסף additional in two different meanings, (a) not radical but formative; (b) not essential but superfluous. פנימי inner (1 Kings 6:27).
