Middle Irish cais could mean love or hate—and a separate cais meant eye.
eDIL's first numbered cais headword is explicitly explained as both love and hate. Its glossary evidence equates the form with serc and grádh on the love side and miscais or mioscais on the hatred side; cited passages likewise cross the divide. Most strikingly, one Éigse line is tentatively translated "my love ... is met by hatred(?)", placing the same visible form on both sides while preserving the editor's question mark. Then eDIL's second numbered cais headword breaks the spell entirely: it means eye. The unveiling is not that love and hate were secretly identical. It is that written identity, lexicographic grouping, contextual meaning, and historical ancestry are four different claims.

Headword 1 cais; Metr. Gl. D 60 and Ff 76; RC xiii 221.4; O'R Poems 2141; ACC 51; O'Cl. glosses; Éigse i 86.8Establishes the dual gloss, supplies located love and hatred evidence, and preserves the same visible form on both sides of the tentative Éigse translation.

SCHOLARLY DISAGREEMENT
DISPUTE POSITIONS THAT CITE THIS SOURCE
opensupportsproposed
Does the Éigse line certainly use cais once for love and once for hatred?
Not certainly. eDIL tentatively translates "mo chais is cais 'na agaid" as "my love ... is met by hatred(?)" and prints a question mark on the second reading.
Éigse i 86.8, mo chais is cais 'na agaid; translation ending hatred(?)Preserves the same-form opposition with the editor's question mark.
opensupportsproposed
Are the opposite readings one polysemous word, merged historical homonyms, or a lexicographic convenience?
eDIL groups them in one headword but does not, by that editorial act alone, settle the full historical relationship among every love and hate occurrence.
Numbered headword 1 cais and its double glossary equationsSupports shared lexicographic treatment.
opensupportsproposed
Did love develop into hate, hate into love, or both from another meaning?
No reviewed source establishes one direction. The citations show an opposition; they do not date a semantic transition.
Love and hate explanation plus mixed citation inventoryDocuments semantic opposition without a dated change sequence.
opensupportsprobable
What is the earliest surviving use of cais in either sense?
Not established here. eDIL supplies located citations but the underlying objects and dates were not normalized or directly inspected for an earliest-use audit.
Located citation inventory under headword 1 caisSupplies evidence locations without a verified first-use claim.

How was historical cais pronounced in each cited period and region?
Not directly recoverable from the reviewed evidence. Written forms and variants do not constitute recorded audio or a complete phonological reconstruction.
Forms caise and written citation variantsSupplies written evidence but no directly recorded pronunciation.
resolvedsupportsestablished
Did cais mean only hatred?
No. eDIL explicitly says the noun is explained both as love and hate, gives love glosses such as serc and grádh, and cites passages translated with love or beloved.

Did cais mean only love?
No. eDIL also gives miscais and mioscais hatred glosses and cites passages translated with hatred.

Are love and hate merely two modern search results rather than one lexicographic headword?
No. eDIL places both explanations, glossary equations, and citations inside headword 1 cais, also caise.
Entire numbered headword 1 cais, forms caiseGroups both explanations inside one lexicographic headword.

Can context assign a reading in every cited passage?
Context can support many readings, as eDIL's translations show, but the entry expressly says texts may be capable of either meaning according to context and some records remain un-translated or tentative.
Entry explanation and located positive, negative, and tentative citationsShows both contextual assignments and unresolved cases.
resolvedsupportsprobable
Does the contrast miscais prove that bare cais originally meant love?
No. The contrast is evidence that some contexts oppose the forms, but prefixal morphology and a translated contrast do not by themselves recover the oldest sense of bare cais.
cin cais, cin miscais; ni tongar ar cais ... na miscais; cen cais, cen miscaisDocuments the contrast without dating or explaining its morphological history.
resolvedsupportsprobable
Does negative caisgen reveal the timeless core of cais?
No. The compound supplies one negative formation, not a license to reinterpret every positive citation as concealed hatred.
Fianaig. 16 §42, dremhan an caisgen tibhesSupplies the negative compound beside the entry's positive evidence.
resolvedcontextestablished
Do the displayed citations measure how often speakers used love versus hate?
No. They are a selected historical-dictionary evidence surface, not a balanced corpus or a sample of medieval speech.

- Koch compares Middle Irish cais with Proto-Celtic *katsi-. The reviewed evidence does not publish a complete, dated chain of Goidelic sound changes, so no missing intermediate forms are invented.
- MEANING
- The attested Irish entry carries both love and hate readings. The reconstruction does not identify which reading is older or prove that the opposition was already present in Proto-Celtic.

LOVE AND HATE MEET INSIDE A PROPOSED CELTO-GERMANIC COMPARISON
Koch places Middle Irish cais and Gothic hatis inside a wider *kad- comparison. eDIL securely documents the Irish love-and-hate field, but Liberman challenges semantic unity across the deeper set. This is a dispute bridge between dossiers, not a genealogical edge or proof that love and hate were once one universal idea.
