Etymology: "Tricoordinate" is a straightforward compound: the prefix "tri-", meaning three, joined to "coordinate". The prefix comes from Latin "tres" and Greek "treis", both meaning three, which is why the same number-sense turns up across so many scientific and technical words. "Coordinate" itself derives from Latin "co-" (together) plus "ordinare" (to arrange), so the whole word literally describes three things arranged together in an order. The word is a technical coinage built on these familiar parts, used mainly in chemistry and geometry to describe arrangements of three linked units. Its meaning therefore follows directly from its parts rather than shifting from an earlier sense.
