# Light and shadows, sentence 2

<!-- .ven lang=en -->
When something blocks the light, it leaves a dark patch behind it in its own outline: a shadow, like your hand rabbit on the bedroom wall.

<!-- .vintro -->
**Who acts:** something, Light · **What happens:** block, leave · **To what, where:** light, dark patch, patch

<!-- .vabout -->
This is a sentence of the lesson «Light and shadows» 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 (something, Light), 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): 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.
