THE TIMELINE ATLAS
JOURNEY ATLAS ↗FORM / ROUTE / BOUND
1398 REVIEWED EVENTSLANGUAGE
IN TIME.
One cross-word chronology for every defensibly bounded form and journey stage—without converting a vague historical label into a fake year.
A reviewed graph bound, not a claim of an earliest human word.
Only stages with directly cited numeric bounds enter this atlas.
Labels remain visible in Journey Atlas, but not parsed into false years.
005 MATCHING EVENTS
FILTER THE CHRONOLOGY
WHEN DID THE EVIDENCE LAND?
TWO CLOCKS.
NO FALSE PRECISION.
FORM CHRONOLOGY dates a canonical linguistic form or reconstruction in the lexical graph.
ROUTE CHRONOLOGY dates a geographic or transmission stage in a word’s journey.
They can share an era band, but they are never silently treated as the same kind of claim.

4500 BCE–2500 BCErange
ROUTE STAGEProposed Indo-European linguistic horizon
cais
*kad- and *kad-t/si-
The deepest displayed route is a cross-branch comparative proposal. No archaeological point, single speech community, or original love-versus-hate meaning is asserted.
1300 BCE–800 BCErange
ROUTE STAGEProto-Celtic linguistic horizon
cais
*katsi-
Koch reconstructs a Celtic formation compared with Middle Irish cais and Old Welsh cas. The graph does not invent a fully dated Goidelic sound chain.
1 EVIDENCE LINK
The interval follows the atlas's conventional Proto-Celtic language horizon, not a directly attested word date.

cais and caise
eDIL groups citations capable of love or hate readings under its first cais headword. Individual cited objects and composition dates were not normalized or directly inspected.
2 EVIDENCE LINKS
A conventional Middle Irish language-stage range; it is not an earliest-use claim for the headword or either sense.

cais
compounds, glosses, and contextual readings
eDIL's evidence surface reaches beyond a single period and includes glossary equations and poetic citations. This stage records transmission and editorial grouping, not a semantic migration.
2 EVIDENCE LINKS
A broad later citation horizon within the dictionary's historical scope, not dates assigned to every quoted line.

eDIL published online in 2007; revised 2013–2019
The searchable digital edition exposes headwords, variants, definitions, citations, translations, and references, while its About page says revision is targeted rather than globally uniform.
1 EVIDENCE LINK
The bounds describe publication and revision milestones of the evidence surface, not the historical life of cais.
AUDIT RECORD ↗UNBOUNDED IS
A REAL RESULT.
Stages without source-backed numeric bounds stay in their complete Journey Atlas route, carry an explicit temporal note, and remain absent here until the evidence supports normalization. The missing point is visible work—not permission to guess.
