Type Anatomy: Bracketed / Unbracketed vs. Adnate / Abrupt Serifs

[rkeller]

Hi

I'm reading about serifs and how they are connected to the stem. I come across the term pairs bracketed / unbracketed and adnate / abrupt.

Are bracketed serifs the same as adnate serifs, or vice versa, are unbracketed serifs the same as an abrupt ones? Are these term pairs interchangeable?

Thanks

Yes, the terms are synonymous. But adnate and abrupt feel dated now (IMO). I much prefer the more descriptive bracketed and unbracketed.
