Is my memory correct that FL developed its own list of lemmas and roots rather than using a specific lexicon in the interlinears? Thanks.
That would be true for resources using the three Logos morphologies (incl. reverse-interlinears), but I don't know if it was based on a specific lexicon. Roots are only available in the Logos morphologies.
Lemmas in the Logos Greek Morphology tend to follow BDAG.
Roots are a little more complicated. The groupings of lemmas are based on a number of things, notably Middle Liddell, Greenlee's morpheme lexicon, and Warren Trenchard’s The Student’s Complete Vocabulary Guide to the Greek New Testament. The labels we use for the root are essentially the shortest noun or verb of the group, unless something else makes more sense. Determining a "root form" gets hinky pretty quickly, and we decided it would be more useful to have a familiar form for the root than something theoretical (it was also much easier).
Thank you Rick. That's what I needed.
It may be obvious, by my comments are only applicable to Greek lemmas and roots.
Hebrew and Aramaic lemmas tend to prefer forms from HALOT.
Hebrew and Aramaic roots are a different story and were developed in-house. I don't have any resources to point you to for reference on those.
