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.

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.

guest
13th c. core noun onward; later extensions
The hospitality recipient remains the core English guest, with later customer, program, performance, biological, and material-science extensions.
1 EVIDENCE LINK
The open interval begins with the source-reported thirteenth-century core noun. It does not assign that onset to every later extended sense.

conscience
13th century–today
Conscience centers on moral judgment while awareness and consciousness remain recoverable historical senses.
2 EVIDENCE LINKS
The open interval begins with the lexicographic English horizon and does not claim uniform global adoption.

Nescience remains an uncommon learned noun for ignorance or lack of awareness.
1 EVIDENCE LINK
The interval begins at the reviewed English horizon; it does not date every later occurrence or variety.
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.
