You know, everywhere you go people state that mAa.t means "justice, truth, order, and balance." However, when I look at all of my dictionaries, they never define mAa.t as "balance." I wonder why? Now, mAa.t has a dialectical variant /mxA/ "balance, level." But we never see the mAa.t form rendered "balance, level." We should note that the graphemes <a> and <x> interchange, or I should say, correspond to each other. So what you are seeing is metathesis on the syllables with the same m- prefix. Morning randomness.
To show that <a> and <x> correspond:
Aa.y “power, might, potency, strength”
Ax.w “power” (of God), “mastery” (over work)
m.Aa “water”
w.Ax “body of water” (in the Netherworld)
Aaa “to gibber, to speak” (foreign language)
Ax.w “spells; magical creative power”; “power (of god), magic, magical words, useful knowledge, mastery”
m.Aa.w “vessel”
Ax.t “a libation vessel”
m.Aa “place”
ra "storehouse, chamber, barracks" (Budge, 419a)
Ax.yt “a room” (storeroom?)
ra "weapon, tool, working-instrument, arms, armour" (Budge, 419a)
Ax.w “(unknown)” [glyph has a knife determinative] (Vygus, 2012: 2244) Z7 - G25 - J1 - T30
m.Aa.w “products, offerings, tribute, gifts”;
Ax.wt “property, goods, possessions, thing, supplies”
Keep in mind as well that /r/ and /A/ interchange in ciKam as well.
should note that a cognate in Kikongo does mean balance: i.e., Kikongo ki.nenga "balance"; lunga "balance" [IsiZulu lunga "balance"]. Middle-Egyptian /A/ corresponds with Bantu /l/ and /n/. Note as well that M-E /a/ corresponds with Bantu /ng/, /g/, and /k/.
