Tafsiran Keluaran 2:9: Rashi, Chizkuni, Rashbam & Siftei Chakhamim

היליכי (the word may be explained as a compound of two Aramaic words, הי, here is, and ליכי, that which belongs to thee — thine own) — she prophesied without knowing what she was prophesying (unconsciously she stated the actual fact) — here is thine own (Exodus Rabbah 1:21 and Sotah 12b).

היליכי, some commentators claim that this word is from the root הלך as in הולכה, the letter י taking the place of the letter ו. Similar examples occur with the mode: ,היטיבי .היניקי

ותניקהו, There is no need to assume that we are dealing with a two-letter mode of the verb as in שב, בא, or קם, and that the letter י of the root ינק is missing here as is usual in the transitive form, הפעיל of the roots קום or שוב, so that we have the construction ותקימהו “she made him stand up,” or ותשיבהו, “she brought him back.” The root we are dealing with here is the verb ינק, and in order to shorten the word somewhat the Torah writes instead of ותיניקהו simply ותניקהו.
