A link on this page was opened in October 2026 and the licence line is what that page said then.

Wikipedia text is CC BY-SA. The GRETIL e-text page states CC BY-NC-SA 4.0. The data README asks for credit and states no SPDX.

Vasu's English was not confirmed, so no words from it appear. Confirm before relying on any meaning you add later.
