## Where it stands

**Disputed** Three pieces of evidence for, two against. It needs two reviews to be accepted.

## What it predicts

- Regular sound correspondences link Iberian words to reconstructed Proto-Basque beyond the numerals.
- Iberian morphology (suffixes, possible ergative marking) matches Basque patterns.

## What would rule it out

- Proto-Basque reconstruction shows the matching Basque forms are late, so the resemblances cannot be inherited.
