Ibn Ezra on Genesis 27:25/אבן עזרא על בראשית כ״ז:כ״ה
אואכלה מציד בני. האל"ף סימן המדבד, והנה הנעלם שהוא אחריו תחת אל"ף השרש, וכן "אומרה לאל כלעי" (תהלים מב י),
1AND I WILL EAT OF MY SON’S VENISON. The alef of ve-okhelah (and I will eat) is a first person imperfect prefix. It is vocalized with a cholam to compensate for the missing alef of the root.31 (eat) is alef, caf, lamed. The alef prefixed to a verb in the first person imperfect is usually vocalized with a segol. I.E. points out that in okhelah the alef is a first person imperfect prefix and is vocalized with a cholam rather than a segol to make up for the missing root letter. We find the same in the word omerah in I will say (omerah) unto God my Rock (Ps. 42:10).32 (say) is alef, mem, resh. In omerah the alef is the alef of the first person imperfect prefix and it, too, is vocalized with a cholam to make up for the missing alef root letter.
בדגשות נו"ן תברכני (בראשית כז יט) לחסרון נו"ן הנוסף כמו "יסובבנהו" (דבר' לב י) וכן "ישחרונני" (הושע ה טו):
2The nun of tevarakhanni (may bless me) (v. 19) receives a dagesh to make up for the missing nun33 is added to the end of the root. Since ni is the sign of the first person pronominal suffix, tevarakhanni should have been spelled with two nuns (we have spelled it with two nuns because of the dagesh. In the Hebrew it has one nun). It should be noted that I.E.’s comment is misplaced as it pertains to verse 19. which should have been in our word, as we find in yesovevenhu (He compassed him about) (Deut. 32:10) and similarly in yeshacharuneni (they will seek Me) (Hos. 5:15).34 we see that a nun is added to the root when a verb is combined with a pronominal suffix. In yeshacharuneni we see that when a verb is combined with a first person pronominal suffix, two nuns are added to the root.
