Bottom line
Heini (yani) works on what has not yet come about: restrain, hold back, stop a plan from being carried out. Heifer works on what already exists: annul, break, crumble a standing legal reality out of being. That is why Bamidbar 30 uses both of a husband nullifying his wife's neder: he heinis her plan and heifers the vow (Rabbi Shlomo Aharon Wertheimer). Batel is the Rabbinic word, largely Aramaic in origin: void, and by extension idle, futile. The trap is rendering heini and heifer both as "annul" in a single pasuk, which is the one place the Torah is distinguishing them.
Distinctions
heini (הניא), yani (יניא)
Rabbi Wertheimer: heini removes something that may not yet have come into being. Tehillim 33:10 is his proof: Hashem heini the designs of the peoples (machshevos amim), and because those thoughts are merely abstract ideas representing only a potential for something to happen, their cancellation is heini.
The word's basic sense was already disputed among the early grammarians. Menachem Ibn Saruk: to break. Dunash Ibn Labrat, following Rav Saadia Gaon: to deny or withhold. Rashi (to Bamidbar 30:6) follows Dunash; Ibn Ezra (to Shemos 12:9, Bamidbar 14:3, Bamidbar 30:6, Tehillim 141:5) follows Menachem, though he also seems to treat heini as equivalent to heifer. Rabbi Yaakov Tzvi Mecklenburg weighs the two at length, framing the question as whether heini is the removal of the will (Menachem) or the withholding of the will's fulfillment (Dunash). The article notes that a century after Menachem and Dunash the controversy was still raging, and its closing footnote points the reader to Rabbi Dr. Yosaif M. Dubovick, "'Oil, which shall not quit my head': Jewish-Christian Interaction in Eleventh-century Baghdad," Entangled Religions vol. 6 (2018), on yani in Tehillim 141:5 and the historical controversy the question generated.
Rav Hirsch (to Bereishis 12:10-13) links heini to the similarly spelled na, raw, half-cooked, the common idea being interruption or stopping: cooking cut off partway, a vow's fulfillment hindered and impeded (so too Midrash Sechel Tov to Shemos 12:9). The article calls the association somewhat questionable all the same: heini and yani are generally spelled with an aleph, like na, but Tehillim 141:5 has yani without one.
heifer (הפר), hafarah (הפרה)
Rabbi Wertheimer: heifer cancels something that has already come into being, and the word is kin to pur, a crumb, since hafarah breaks a standing thing into pieces and grinds it out of existence. So one who abrogates a mitzvah (Bamidbar 15:31) or a covenant (Yeshayahu 44:25) is like a man tearing up a binding contract.
On the two words in the parashah of nedarim: the father or husband accomplishes two things at once. He stops the woman from doing what she undertook to do, and he dissolves the legal standing of the vow. The Torah says heini of the first, since what she meant to do has not yet come about, and heifer of the second, since the vow's legal reality exists and can therefore be broken.
The article reports Malbim as explaining similarly: heini refers to forcing something out of existence, while heifer refers to simply ensuring that something will not come to fruition, without necessarily using force.
batel (בטל)
The standard Rabbinic verb for nullification: bitul Torah, idleness in place of learning; bitul chametz, declaring one's chametz void before Pesach; bitul b'rov, a forbidden food nullified in a majority. From the futility in batalah the word came to cover whatever seems purposeless. Its root appears to be of Aramaic origin: seven occurrences in Tanach (Koheles 12:3 and six times in Ezra 4-6), against more appearances in the Targumim. The article floats, as its own suggestion, a conceptual tie to tal, dew, which comes at dawn and is gone.
Rendering guidance
- In Bamidbar 30, distinguish: heini is "restrain" or "hold her back"; heifer is "annul" or "void." "He annulled her vow and restrained her" keeps both alive.
- Tehillim 33:10 has both verbs, and the pairing is worth keeping visible: the heini clause is "He frustrates the designs of the peoples," where there is no standing instrument to annul. Do not attach "annuls" to that clause.
- Heifer bris (Yeshayahu 44:25 and its like): "broke the covenant," which keeps the pur image; "violated" loses it.
- Batel and bitul stay transliterated in halachic contexts (bitul chametz, bitul b'rov, bitul Torah) with a gloss at first use. In plain prose, "void" or "nullified."
- Trap: English "nullify" will swallow all three. Where a source is reading the Torah's switch between heini and heifer, keep the Hebrew visible; a translation that says "annul" twice has erased the derashah.
- Batalah in a mussar passage is "idleness," not "nullification"; the two senses of the root do not travel together into English.

The closing footnote to Rabbi Dr. Yosaif M. Dubovick's study of the eleventh-century controversy over yani in Tehillim 141:5 had been dropped from an earlier version of this entry under a mistaken sources rule; it is restored above. The tie between batel and tal is the article's own suggestion, not an authority's, and is marked as such above.
Two corrections made in this pass. The entry had reported Malbim as reversing Wertheimer's labels and had advised checking Malbim inside before citing him. The article says the opposite: "Malbim similarly explains." The article reports no dispute here, so neither does the entry, and the advice, which was not the article's, is cut. The entry had also given the heini of Tehillim 33:10 as applying to "the counsel of the nations." In the pasuk that phrase (atzas goyim) takes heifir; heini takes machshevos amim, which is the clause the article describes as the abstract thoughts.
