Feind
The modern German noun for a personal, political, military, or ideological enemy or opponent. Duden derives it through Middle High German vīnt or vīant and Old High German fīand, literally the hating one; DWDS dates Old High German fīant and fījant to the eighth century and identifies the Germanic ancestor as a petrified substantivized present participle. Grimm’s dictionary independently compares Gothic fijands, Old English fēond, English fiend, Dutch vijand, and Nordic forms, while warning that its own still-deeper foam hypothesis required confirmation. The reviewed route therefore follows the inherited enemy noun to reconstructed *fi(j)and- and *fi(j)ēn-, then treats *peh₁- as proposed and stops.

Freund
German Freund continues Middle High German vriunt and Old High German friunt. DWDS/Pfeifer, Duden, and Grimm independently analyze the inherited Germanic formation as a substantivized present participle of the verb represented by Gothic frijōn and Old English frēogan: historically a loving or favorably disposed one. The record is semantically wider than a modern close companion: the historical dictionaries also document neighbor, relative, lover, ally, supporter, patron, address, and euphemistic uses. The graph joins the High German line to the same reviewed *frijōnd- and *frī- nodes as English friend, keeps *prī- proposed, and stops.

Hass
The modern German noun for intense aversion, rejection, or hostility toward a person, group, or institution. Duden traces Middle and Old High German haʒ to suffering, sorrow, and resentment and records the 1996 spelling change from Haß to Hass. DWDS/Pfeifer reports the Old High German noun from the eighth century and places it in the Germanic family of Old Saxon heti, Old English hete, Old Norse hatr, Gothic hatis, and related forms. Grimm’s DWB preserves a more complicated semantic record: hostile pursuit or action, anger expressed in deeds, ordinary hostile disposition, and even measured rivalry during friendly competition. The reviewed route reuses *hatiz- and the qualified *ḱh₂d-es- / *ḱeh₂d- comparison, then stops.

WHERE INTERPRETATION IS TESTED
CLAIMS & DISPUTES
SCHOLARLY DISPUTES / 12
openproposeddispute-title prefix
Is the deepest root *leǵ- or *sleǵ-?
The traditional *leǵ- reconstruction remains widely represented, while published scholarship argues that the gather or collect root began with *s. The graph preserves both analyses.
openprobabledispute-title prefix
Is the exact phonetic shape of *fi(j)and- directly known?
No. The form is a comparative reconstruction. Optional j notation, branch vowels, and the relation of written historical variants require analysis rather than direct Proto-Germanic observation.
openproposeddispute-title prefix
Is the deepest *peh₁- route established?
No. The Germanic verb and lexicalized agent formation are firmer than the proposed Indo-European comparison, whose formal intermediates and semantic unity remain reconstructive.
openprobabledispute-title prefix
Is the exact Proto-Germanic noun *hatiz- or *hataz?
The noun is reconstructed, and published notation reflects stem alternation and analytical choices. Koch prints *hataz ~ *hatiz- while Merriam-Webster foregrounds *hatiz-.
openproposeddispute-title prefix
Is the deepest counting root *h₂rei- or *erei-dhmo- from *re-?
The references use different levels and notations: Merriam-Webster derives the Greek base through *h₂rei-, while Etymonline prints an expanded *erei-dhmo- formation tied to *re-.
openproposeddispute-title prefix
Is Choctaw bayuk a securely attested source of bayou?
No. An early Choctaw *bayok is plausible and accepted in a major handbook, but later bayuk is not securely attested and contraction to bók was conjectural.
openprobabledispute-title prefix
Is betroth built on truth or troth?
The historical base is Middle English trouth or trouthe, where the modern truth and troth spellings were not yet cleanly separated; mapping it to only one modern headword overstates the evidence.
openproposeddispute-title prefix
Is Proto-Celtic *katsi- the secure direct parent of cais?
Koch publishes the comparison, but the reviewed materials do not expose a complete dated Goidelic derivation or independent consensus sufficient to mark the edge established.
openproposeddispute-title prefix
Is *kad-t/si- from *kad- the only defensible deeper analysis?
No. It is a published proposal, not an attested sequence, and the wider cross-branch set remains semantically disputed.
openproposeddispute-title prefix
Is calculus securely a diminutive of calx “limestone”?
Not securely. The traditional analysis is morphologically and semantically irregular; an alternative links Latin calculus and Greek stone words through a possible shared substrate source.
openproposeddispute-title prefix
Is Latin calculus securely a diminutive of calx?
No. Festus accepted the traditional limestone derivation, but the phonology and meanings are problematic. The edge remains proposed.
openproposeddispute-title prefix
Is the deepest brightness root *kand- or *(s)kend-?
The graph preserves both published analyses. The newer Merriam-Webster route uses *(s)kend- and explains candēre through a zero-grade stative formation; the prior *kand- route remains proposed.
CONTRARIAN TRUTHS / 12
RANK 1GRADE Aranked reveal
A stranger became both guest and enemy.
The reciprocal outsider behind guest and host also became Latin hostis, “enemy.”
RANK 3GRADE Aranked reveal
Robot named forced labor before machinery.
The machine word begins in Czech robota: compulsory labor, corvée, or drudgery.
RANK 4GRADE Acontrarian claim
Humility is an earth-and-lowness metaphor.
Latin humus “ground” produced humilis “low,” then humilitās “lowness,” before the moral virtue.
RANK 5GRADE Aranked reveal
Calculation began with a pebble in the hand.
Latin calculus was a small stone used for reckoning before calculation became abstract.
RANK 6GRADE Aranked reveal
Evidence became a thread you could follow.
Old English cliewen was a ball of thread; the labyrinth metaphor turned it into guidance through uncertainty.
RANK 7GRADE Aranked reveal
Nice crossed from ignorance to approval.
Latin nescius “ignorant” became foolish or wanton, then fastidious and precise, and finally pleasant or kind.
RANK 8GRADE Aranked reveal
Etymology calls itself the “true account.”
Greek ἔτυμος “true, real” joined -λογία “account or study”; even that truth-word reaches a reconstructed root.
RANK 9GRADE Acontrarian claim
The most repeated origin story is not the most rigorous answer.
Mapuche ancestry is a serious, evidenced proposal—but current RAE and a historical Spanish argument keep the deeper source genuinely open.
RANK 10GRADE Acontrarian claim
Andean neighbors need not be linguistic cousins.
Alpaca comes from Aymara while llama comes from Quechua: the words travel through Spanish from different families.
RANK 11GRADE Aranked reveal
It was never humanity’s universal ancient name for spiritual practitioners.
English globalized a specific Evenki term through European scholarship and applied it to many unrelated traditions.
RANK 12GRADE Acontrarian claim
A Turkish word is not proof of who invented the food.
English yogurt is Turkish yoğurt, probably related to yoğur- “knead”; the origin of fermented milk is a different historical question.
RANK 13GRADE Acontrarian claim
Legislation came before legislate.
The noun preserves a Latin law-bearing or law-proposing compound. English legislate was later back-formed from the already existing noun family.
