<!-- .vintro -->
**Who acts:** Sun, tiny parts, process · **What happens:** shine, join, call, keep · **To what, where:** Sun, fusion · **Speech:** someone speaks here

<!-- .vabout -->
This is a sentence of the lesson «Fuels, the Sun and saving energy» of the physics course of Mova's primary school. The page gives its syntax tree — a dependency tree in the style of Universal Dependencies — and its pragmatics clause by clause: who acts (Sun, tiny parts, process), what happens, when and where, as Mova's frames read it from the tree.

**The tree:** Mova annot: Rust (en) → Haiku 5.5 (medium, Batches API) patches; gates UD 2.18; agreed by treeagree rules (Stanza, Trankit, spaCy trf): R5-strong ×1, R6-punct-agree ×1, R7-rel-agree ×1. **The frames** are read from the tree by Mova's frames reader (`prag`) when this page is built, the lesson read in order, so a pronoun may be resolved from an earlier sentence.
