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.
FILTER THE ROUTE ARCHIVE
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
CALCULATE ON THE MAP
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.

Latin calculus and counting-board practice
Latin calculus names a pebble, a pebble used on a counting board, and the resulting method or account. That physical-computation link is secure; the deeper derivation from calx “lime, limestone” is explicitly uncertain.
2 DIRECT CITATIONS ↗ - 02late antiquity–medievalNO SINGLE PIN
Late Latin calculating family
Late Latin calculātus is the past participle of calculāre “count, reckon, compute,” derived from calculus. The route keeps this learned formation distinct from the unsettled prehistory of the stone word.

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.
