I have already posted some discrepancies I've seen with the word list here: https://community.logos.com/forums/t/189857.aspx
In that post, they recommended I add lemmas from a Hebrew Bible rather than an interlinear like the NKJV. When I added lemmas from the LHB, I noticed there were some words missing that were common in the NKJV. Upon further investigation, it appears that adding lemmas from the LHB does not include Aramaic lemmas, whereas adding lemmas from the NKJV does include Aramaic lemmas (for example, דִּי).
For a simple demonstration, try adding lemmas from LHB Ezra 4:8 (which is all Aramaic). Nothing shows up. Then add lemmas from LHB Ezra 4:7 (which is in Hebrew). 19 lemmas show up. Then delete everything and add lemmas from Ezra 4:7-8. Again, 19 Lemmas show up, all from Ezra 4:7.
