ADDRESSES.
Trace where a word’s reviewed history passed through—and see every broad, global, or uncertain stage that cannot honestly be reduced to one point.
A ROUTE IS A MODEL.
NOT A GPS TRACE.
Regional pins locate reviewed cultural stages. Approximate pins locate broad reconstructed or contact regions. Global stages stay unpinned. Every route preserves its full editorial sequence; only directly cited, explicitly bounded stages also enter the cross-word Timeline Atlas.
231 coordinate pairs exist; global placements are suppressed.
Broad, global, uncertain, or not honestly reducible to one point.
1324 claim-level citations; every remaining stage is a frontier task.
Source-backed stages now join the cross-word Timeline Atlas.
Historic labels remain readable without being parsed into false years.

WHERE DID THE WORD GO?
Filters select complete word journeys when any stage matches. The map and route card then preserve the surrounding stages, so a search result never becomes a historically amputated dot.
THE REVIEWED GEOGRAPHIC LAYER
WORDS DO NOT MOVE IN STRAIGHT LINES.
This is not a GPS trace. Lines appear only when adjacent stages in one selected route both have defensible points. A global stage is not pinned even when a legacy coordinate names the route’s point of departure. Missing locations break the line.

England

English-language decimate senses
The drastic-reduction and severe-destruction senses are not a recent mistake: Merriam-Webster reports that the broader meaning arose within a few decades and has been used steadily since the seventeenth century.

disaster
OPEN DOSSIER ↗- 01Latin antiquity; later astrological inheritanceNO SINGLE PIN
Latin astrum and the astrological frame
Latin astrum names a star or constellation. The later disaster family preserves the once-literal astrological idea of an unfavorable planetary or stellar aspect, but the lexical sources do not locate that semantic development at one Roman point.
2 DIRECT CITATIONS ↗ - 02Old Italian stage; exact onset unresolvedregional placement
Italy
Old Italian disastro combines the negative prefix dis- with astro “heavenly body.” It could still denote an unfavorable stellar or planetary aspect before the calamity meaning generalized.
1 DIRECT CITATIONS ↗ - 03Middle French borrowing; exact onset unresolvedregional placement
France
Middle French desastre borrows the Italian calamity word. Merriam-Webster treats both French and Italian as part of the English borrowing history rather than forcing a single donor label.
1 DIRECT CITATIONS ↗ - 041567 first-known-use horizon onwardNO SINGLE PIN
English-language disaster senses
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.

WHAT THIS MAP CAN AND CANNOT CLAIM
GEOGRAPHIC HONESTY IS PART OF THE DATA.
A defensible cultural or linguistic region can be plotted, but the point summarizes an area rather than an exact address.
A reconstructed homeland or contact zone is placed only as a broad visual orientation and uses a distinct dashed marker.
A distributed network, era, or world language has no honest single coordinate. It remains in the sequence and off the map.
Directly cited stages may carry exact, range, century, circa, open, or before bounds. Unbounded prose stays unparsed.
959 stages have claim-level citations and 578 have defensible numeric bounds. Every uncited or unbounded stage remains visible unfinished work.
