A-affection in Adûnaic

What is your opinion on the occurrence of A-affection in Adûnaic — especially in the situation when one derives masc. karbû and fem. karbî type forms from karab-like nouns whose root vowel is not A, but instead I or U?

Does the attestation dolgu indicate that in such a case I > E and U > O, or should one instead follow the "lead" of kulb-ô, -â, -ê, -û, -î in SD:425?

Select Primitive Elvish Roots: I-IT

ᴹ√ “that (deictic particle); [ᴱ√] here it is, root of relatives”

A root in The Etymologies of the 1930s glossed “that (deictic particle)” (Ety/I¹). A similar root appeared in the Qenya and Gnomish Lexicons of the 1910s glossed “here it is” (QL/41) and “root of relatives” (GL/50). Given Tolkien’s long standing use of i for both “the” and the relative pronouns “that” in all his Elvish languages, this root was established very early and remained more or less fixed throughout Tolkien’s life.

Sindarin Phonetics XX: OS. initial [ŋ] became [ŋg]

Starting in the late 1950s or early 1960s, Tolkien decided the ancient velar nasal ñ- [ŋ] was strengthened to ñg- initially in (Old) Sindarin and ultimately became g-. Tolkien seems to have introduced this idea in an etymology of the name of Galadriel written sometime between the first and second edition of The Lord of the Rings:

Polka to i Ramba

Select Primitive Elvish Roots: DAL-ÐOTO

DAL “bottom, ground; [ᴹ√] flat”

This root first appeared in The Etymologies of the 1930s as ᴹ√DAL with the gloss “flat” and various derivatives of similar meaning (Ety/DAL). It reappeared again in later notes as √DAL “bottom, ground” written in the late 1950s or early 1960s (PE17/150). In both places, it had a variant form √LAD of similar meaning.
