820 canonical forms + 578 route stages.
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.
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.
CROSS-WORD CHRONOLOGY / EARLIEST BOUND FIRST
THE EVIDENCE IN TIME
disaster
1567 first-known-use horizon onward
English disaster is recorded from 1567 for a calamitous event and now also applies to failures, harmful results, agitated people, and disorder. The current senses no longer require belief in astrological causation.
The open interval begins with the reviewed 1567 English first-known-use horizon. It does not date each later figurative or evaluative extension to that year.
AUDIT RECORD ↗etymological
current use
The adjective remains current for matters of etymology and etymological analysis.
etymological
1588–1590s source horizons
Two historical dictionaries report close but nonidentical first-record horizons for etymological.
omniscient
1598–today
Omniscient applies to all-knowing beings and, later, narrators whose viewpoint can access every character.
The open interval begins with the reviewed English horizon and does not date the narrator sense separately.
AUDIT RECORD ↗Feind
Feind as personal, collective, military, and ideological opponent
Duden documents the contemporary sense range while DWDS keeps the inherited opponent or adversary center visible.
German is pluricentric and geographically distributed, so the modern language is not reduced to one map pin.
AUDIT RECORD ↗calculus
1666–today
Calculus expands across mathematics, logic, decision theory, medicine, and dentistry.
The interval begins at the reviewed English horizon; later technical specializations are not assigned invented first dates.
AUDIT RECORD ↗чай
Vasmer dictionary record
The etymological dictionary anchors the modern Russian headword and its relay analysis.
1953 marks the cited dictionary publication, not the word’s first Russian use.
AUDIT RECORD ↗ἐτεός
Late Bronze Age contact context; analysis published 2017
The ἐτεο- element also appears in Eteocles, whose cross-linguistic name history motivates a carefully qualified phonological discussion.
2017 dates the reviewed thesis analysis, not the ancient personal name.
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.
