The invertible root √BA or √ABA was principally connected to refusal, and its best known derivative was Avari, the group of Elves that refused to travel to Valinor. When Tolkien first introduced the root ᴹ√AB in The Etymologies of the 1930s and other contemporaneous writings on Ancient Quenya, he gave this root the meaning “go away, depart” (Ety/AB; PE19/045); in this sense it may have been a replacement for the early root ᴱ√AVA “go away, depart, leave” (QL/33). Indeed, the first application of Avari was to the Elves that left for Valinor, “the Departing”, rather than those that stayed behind (LR/169-170). But the sense “away” was soon transferred to ᴹ√AWA (Ety/AWA) and √AB was revised in The Etymologies to mean “refuse, deny, say no” (Ety/AB), a sense it retained thereafter.
Tolkien wrote about this root at great length in the 1959 when he decided that √BA was part of the Eldarin system of negation, distinguishing negation of volition (I will not) from negative of fact (it is not so). Tolkien seems to have introduced this notion at the same time he decided to abandon la-negation, so the corresponding negation of fact was the root √Ū (PE17/143). Even when Tolkien considered restoring la-negation in the late 1960s, √BA still retained a role as the negation of volition (PE22/161).
One peculiar feature of √BA is that it represented refusal from the perspective of the speaker. Thus in 1st person, √BA meant “I will not” (refusal), but in 2nd person or 3rd person it meant “do not” (forbiddance). Tolkien discussed this topic at some length in the Quendi and Eldar essay from 1959-60 (WJ/370-2). In 1st person this was Q. ván(ye)/S. avon “I won’t” and Q. vamme/S. avam “we won’t” [using the circa-1960 pronominal suffix -mme; with later pronouns this would be valve and avof]. In 2nd person this used the interjection Q. vá/S. baw “don’t”, or the negative imperative particle Q. áva/S. avo, as in Q. áva care/S. avo garo “don’t do [it]”.
When Tolkien revisited his ideas for negation in 1969, he still kept this notion of 1st person refusal vs. 2nd/3rd person forbiddance (PE22/161-3), so that the system of √BA negation remained more or less the same (barring changes like new pronouns).

This invertible root and ones like it were the basis for “away” words for much of Tolkien’s life. The earliest iteration was ᴱ√AVA “go away, depart, leave” in the Qenya Lexicon of the 1910s with derivatives like ᴱQ. au “away from” and ᴱQ. avanwa “going, passing, nearly gone” (QL/33). This early root remanifested as ᴹ√AB “go away, depart, leave” in The Etymologies of the 1930s, but the gloss of that root was revised to “refuse, deny” (Ety/AB). As a replacement, Tolkien introduced ᴹ√AWA “away, forth; out” with derivatives like ᴹQ. ava “outside”; Tolkien also considered deriving a privative prefix ᴹQ. ava- from this root (Ety/AWA).
The root √AWA was mentioned many times in Tolkien’s later writings, along with its inverted variant √WĀ, usually with the sense “away (from)” or a verbal sense “go (away), depart, pass away”. Its most detailed description appeared in the Quendi and Eldar essay of 1959-60, where Tolkien said:
> The element ✱AWA ... referred to movement away, viewed from the point of view of the thing, person, or place left. As a prefix it had probably already developed in CE the form ✱au-. The form ✱awa was originally an independent adverbial form, but appears to have been also used as a prefix (as an intensive form of ✱awa-, ✱au-). The form ✱wā- was probably originally used as a verbal stem, and possibly also in composition with verbal stems (WJ/361).
In this same document Tolkien said of Sindarin that:
> The only normal derivative [of √AWA] is the preposition o, the usual word for “from, of”. None of the forms of the element ✱awa are found as a prefix in S, probably because they became like or the same as the products of ✱wō, ✱wo (WJ/366).
Indeed, most of the attested derivatives of this root are in Quenya, but there are a couple in Sindarin, such as the aforementioned S. o from AWA, as well S. gwanwen “departed” (WJ/378) and the verb S. gwae- “go”, probably only in the limited sense “depart” (PE17/148), both from WĀ.
In late notes from 1969 Tolkien gave the root √AWA the sense “before or ago (of time)” (PE22/167 note #117; PE22/168), but I suspect this was a transient idea.
