Helium is lighter than air, so helium balloons float; it was first found in the Sun's light, and its name comes from the Greek for "Sun".

Who acts: Helium, helium balloons, name, Sun · What happens: be, float, find, come, light, name · To what, where: Helium, light, Greek

This is a sentence of the lesson «Elements and the famous members of the periodic table» of the chemistry 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 (Helium, helium balloons, name, Sun), 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): R6-punct-agree ×2, R8-pos-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.
