Definitions

1. Impossible to show or represent in a diagram, such as a structure or process too complex or irregular to be drawn

Etymology: "Undiagrammable" is simply the English prefix "un-" ("not") attached to "diagrammable," meaning something that cannot be represented in a diagram. The base word "diagrammable" is built from "diagram," which comes from Latin "diagramma," borrowed from Greek "diagramma" ("that which is marked out by lines"), itself from "diagraphein" ("to mark out"), and the suffix "-able," meaning capable of being done. Put together, the word describes something that resists being turned into a diagram, such as a relationship, a sentence, or a set of ideas too tangled or abstract to map onto boxes, arrows, and lines. It is a transparent formation, so its meaning follows directly from its parts.
