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.

English intelligent appears in the reviewed lexicographic record for mental capacity.

The ten-year interval encodes circa 1540 as an approximate lexicographic horizon, not proof of coinage.

The adjective expands across judgment, rationality, life, systems, machines, and computer-guided devices.

The open interval begins at the reviewed English horizon without assigning invented dates to later technical senses.
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.
