Appropriate for what? The podcast covers soooo much and attempts to catalog all influences from proto-indo-European onward, with a focus on shared word origins and phonetic changes over time. So some of the pronunciation is speculative reconstruction.

That's what I meant: pronunciation (as best as can be reconstructed) of a word being discussed in a historical context.

Yup, the host goes into that. It covers from the Indo-Europeans up to Shakespeare (where the podcast is at currently). To get an idea of the show's perspective, the host is something of an amateur linguist and historian. So it's the historical and linguistic reasons that English is the way it is.

All time great podcast, IMO.
