## Summary
The paper asks how a listener works out whose point of view a perspectival word is anchored to, using English *come* and *go* as the test case. *Come* signals that some perspective holder (speaker, listener or attitude subject) is at the destination, so the hearer must infer both what happened and from whose viewpoint it is described. The authors extend the Rational Speech Acts (RSA) framework so that the pragmatic listener infers a joint distribution over worlds and perspectives given an utterance. In their lexicon, *come* carries a motion meaning plus an anchoring condition, while *go* carries motion only. A cost applies to non-speaker perspectives. The model yields three predictions:

- *go*'s "away from the anchor" reading can arise as a Gricean inference rather than from its lexical meaning;
- the non-speaker cost parameter shifts which perspective holder is inferred;
- weighing several perspectives at once changes the marginal distribution over worlds.

The work is theoretical and sets out experiments to test these predictions. It matters because it turns perspective resolution into explicit, testable probabilistic inference.

## Key points
- *Come* has two parts: a motion implication (x moves to d) and an anchoring implication (a salient perspective holder is located at d). *Go* has only the motion implication.
- The model has three levels: literal listener, literal speaker (softmax over log L0 minus cost) and pragmatic listener. The pragmatic listener reasons over (world, perspective) pairs, with a uniform prior over perspectives.
- Cost is charged only for non-speaker perspectives, so a non-speaker reading wins only when the semantics rule out the speaker. For "I am coming to Northampton", the listener (Lydia) perspective gets probability 1.0. For "You are coming…", the speaker perspective gets 1.0.
- For "Thera is coming to Northampton" with speaker cost 0.5, the marginal over worlds favours the world where both speaker and listener are at the destination. This holds whenever the listener has a non-zero chance of being the perspective holder.
- The planned experiment is a picture-choice task. It contrasts *coming* with a non-perspectival control (*driving*) to separate the effect of perspective from a general preference for co-located interlocutors.

## Interesting ideas
- Treat the perspective holder as a latent variable that is inferred jointly with the world, rather than fixing it to the speaker by default.
- Derive the "away from anchor" sense of *go* pragmatically, from the speaker not choosing *come*, so the lexicon stays minimal and the inference stays traceable.
- Use lexical semantics to prune impossible readings, since a mover cannot also be the anchor at the destination.
- Marginalise over all live perspectives, so the preferred world is the one that satisfies every plausible reading.
- Build each test item with a non-perspectival twin (*coming* vs *driving*) to separate the target effect from background plausibility.

## For Mova

How these ideas could serve Mova, our small open language model — its files, stages and tests:

- **I1** (frames): Deictic items like *come*/*go*, *here*, *tomorrow* and *my right* could carry an explicit, scored set of candidate anchors (speaker, addressee, attitude subject) instead of a single hard-coded one.
- **I2** (frames): The implicature module could record such contrast-based inferences ("*come* was available but not used") as defeasible, explainable conclusions rather than lexical facts.
- **I3** (world): When placing entities in the text world, *come* can assert the anchor's location only for candidates not already moving in that event, which narrows locations cleanly.
- **I4** (answer): For questions like "where is the narrator?", answers could be ranked by support summed across perspective readings rather than by one chosen reading.
- **I5** (learn): Paired negative-control items like this would show whether a deixis-handling improvement truly comes from the perspective machinery.
