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
taboo
1777 English record
Merriam-Webster reports English first known use in 1777.
The year is a lexicographic first-use report, not proof that no earlier spoken or written token exists.
AUDIT RECORD ↗taboo
1777–today
a ritual or social prohibition; prohibited or set apart
dime
1786 coin-sense horizon
The older tenth-word is applied to the ten-cent coin. Merriam-Webster reports 1786 as the first known use for that sense.
1786 is the reviewed lexicographic first-use year for the coin sense, not proof of the first spoken use.
AUDIT RECORD ↗dime
1786 onward
The coin name continues and develops money, cost, basketball-pass, and accurate-throw senses without losing its ten-based identity.
The interval begins with the reviewed coin horizon; later figurative senses are not all assigned to 1786.
AUDIT RECORD ↗dime
1786–today
a United States or Canadian coin worth ten cents
bumarin
Dharug source candidate
missile or club; proposed source of boomerang
bou-mar-rang
Dharawal source candidate
returning boomerang; proposed source candidate
salt
1790–today
The inherited material word broadens to chemical salts and continues in figurative senses of savor, skepticism, and experience.
Etymonline dates the modern chemical class sense to 1790; older material and figurative senses remain separately described.
AUDIT RECORD ↗humus
humus in 1796
The New Latin term enters English scientific vocabulary.
The date is a source-reported English first-use horizon, not a known coinage event or address.
AUDIT RECORD ↗humus
1796–today
partly decomposed organic matter in soil
nice
19th c. onward
Pleasant and agreeable senses become established in the nineteenth century while precision and fastidiousness senses survive.
The source places the familiar pleasant and agreeable development in the nineteenth century; the interval remains open into current usage.
AUDIT RECORD ↗चाय / چائے
modern Hindi–Urdu
tea
ubuntu
Modern isiZulu
humanity; goodness
ubu-
Modern isiZulu
abstract-noun class prefix
-ntu
Modern isiZulu
human; person stem
ubuntu
Modern isiXhosa
humanity; goodness
tapu
Māori record–today
sacred, prohibited, restricted, set apart, or under atua protection
kapu
Hawaiian record–today
prohibited, forbidden, sacred, consecrated, or set apart
چائے
standard modern Urdu
tea plant, leaves, beverage, infusion, and tea gathering
nice
19th century–today
pleasant, agreeable, kind; also precise or discriminating
science
19th century–today
systematic knowledge, especially knowledge tested through scientific method
fiend
modern fiend
The literal enemy or foe sense is obsolete, while Devil, demon, wicked-person, harmful-thing, and later figurative uses continue in global English.
friend
friend across interpersonal and specialized senses
OED includes companion, ally, supporter, Quaker, climbing device, and social-network contact. Contemporary English is distributed and not reduced to one map point.
A modern semantic continuum, not proof that every sense is equally common.
AUDIT RECORD ↗hospice
1818 English lodging horizon
English hospice is first reported in 1818 for a lodging, especially one maintained by a religious order.
1818 is the reviewed first-known-use year for the lodging sense, not for modern palliative medicine.
AUDIT RECORD ↗hospice
1818–today
a program or facility providing palliative care; historically a lodging or shelter
boomerang
1824 English record and later global spread
Merriam-Webster reports English use by 1824; ANU documents later international and figurative development.
The exact year is the lexicographic first-use report; international spread and figurative senses are later and not reduced to that year.
AUDIT RECORD ↗boomerang
1824–today
an Aboriginal Australian throwing club; later, something that recoils on its originator
icon
1833–today
The Eastern Church sacred-image sense becomes explicit in English historical reporting.
The opening year follows Etymonline's semantic-history report and does not date the older Greek religious practice itself.
AUDIT RECORD ↗kapu
1836 dictionary record–today
Historical Hawaiian dictionaries document kapu as prohibited, sacred, consecrated, and set apart.
1836 is the cited dictionary record, not a claim that the inherited word began then.
AUDIT RECORD ↗ստոյգ
19th-century dictionaries–today
The classical spelling, senses, derivations, and competing etymologies are preserved in Armenian dictionary traditions.
1836 marks the beginning of the New Dictionary of the Armenian Language publication range cited by the lexical tradition.
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.
