# Dictionary

Mova's explanatory dictionary for pupils: `dictionary.tsv`, one word per line, 16,868 words, six tab-separated columns: the word; its part of speech with its forms; its meanings for a pupil (every common sense, numbered); its sense in the lessons (how school word problems use it); examples from the lessons (separated by « | »); a note for the reader of a maths problem. The first line is the header.

**How it was made:** written for Mova by its teacher models from written briefs (one entry per word, in plain English for a clever 9–10-year-old; the maths senses and counted facts such as «A week is 7 days» kept in a fixed form), then checked by Mova's validator (`world dictionary merge`). No dictionary text was copied into it.

**How Mova uses it:** the dictionary course of the school (one lesson per word) and the maths student, which takes counted facts and the operations words signal from it.
