[58a] 1. The pronominal suffixes appended to the verb express the accusative of the personal pronoun. They are the following:—
|To a form ending in||To a form in the Perf.||To a form in the Imperf.|
|a Vowel.||ending in a Consonant.||ending in a Consonant.|
|Sing.||1. com.||־֫נִי||־ַ֫ ני (in pause ־ָ֫ נִי)||־ֵ֫ נִי||me.|
|2. m.||־֫ךָ||־ְךָ (in pause||־ֶ֥֫ ךָ, also ־ָךְ)||thee.|
|f.||־ךְ||־ֶ֫ ךְ ־ֵךְ, rarely ־ָךְ||־ֵךְ|
|3. m.||־֫הוּ, וֹ||־ָ֫ הוּ, (הֹ) וֹ||־ֵ֫ הוּ||him.|
|Plur.||1. com||־֫נוּ||־ָ֫ נוּ||־ֵ֫ נוּ||us.|
|2. m.||־כֶם||־ְכֶם||you (vos).|
|3. m.||הֶם,  ם||־ָם (from ־ָ֫ הֶם, ־ָ֫ ם||־ֵם (from ־ֵ֫ הֶם)||eos.|
|poet.||־֫מוֹ||־ָ֫ מוֹ||־ֵ֫ מוֹ|
|f.||־ן||־ָן, ־ַ֫ ן||.....1||eas.|
[58b] 2. That these suffixes are connected with the corresponding forms of the personal pronoun (§ 32) is for the most part self-evident, and only a few of them require elucidation.
[58c] The suffixes נִי, נוּ, הוּ, הָ (and ךָ, when a long vowel in an open syllable precedes) never have the tone, which always rests on the preceding syllable; on the other hand, כֶם and הֶם always take the tone.
[58d]In the 3rd pers. masc. ־ָ֫ הוּ, by contraction of a and u after the rejection of the weak ה, frequently gives rise to ô (§23k), ordinarily written וֹ, much less frequently הֹ (see §7c). In the feminine, the suffix הָ should be pronounced with a preceding a (cf. below, f, note), as ־ָ֫ הָ or ־ֶ֫ הָ, on the analogy of āhû; instead of ־ָ֫ הָ, however, it was simply pronounced ־ָהּ, with the rejection of the final vowel,
- According to Diehl (see above), p. 61, כֶם occurs only once with the perfect (see §59e), 7 times with the imperfect, but never in pre-exilic passages, whereas the accus. אֶתְכֶם occurs 40 times in Jer. and 36 times in Ezek.—הֶם occurs only once as a verbal suffix (Dt 3226, unless, with Kahan, Infinitive u. Participien, p. 13, אַפְאִיהֵם from פָּאַהּ is to be read), while the forms כֶן (2nd f. pl.) and ־ֵן and הֶן (3rd f. pl.), added by Qimḥi, never occur.
