Oh very good! I keep kicking myself for missing things. Every time.

A lowly four for me on this, but more through stupidity than bad puzzle making. A great grid, thanks.

Elvish - excellent!

Good. Fluked getting 10 - didn't know the full reason why basic fitted into its group, but your link terms were generous. Thanks.

What is Basic here? Google isn't giving me anything

BASIC is a family of general-purpose, high-level programming l******s whose design philosophy emphasizes ease of use. The original version was designed by John G. Kemeny and Thomas E. Kurtz and released at Dartmouth College in 1964

@D I assume Basic here means Galactic Basic, from Star Wars. It's a bit of a fudge, if it's that, but that's all I found except for the computing term.

@D @Midge Galactic Basic Standard, known in-universe as Basic, is indeed from Star Wars. One of those things that people never say the full name of- even I didn't know that's what it was short for, I've only ever heard Basic. It was after getting for the programming languages, along with Java.
