Currently when creating a Morph Query document for the SBLGNT, we can select the Conjunction Subtype, Pronoun Type, Adverb/particle Type, and Pronoun Subtype. Please add the option to select Article Type.
Here is a post where the usefulness becomes apparent. Basically, it is necessary if we want to create a Morph Query document that returns anarthrous or arthrous nouns with accuracy.
The following search is an attempt to return anarthrous instances of ἀλήθεια:
It is missing 1 hit, in 2 Corinthians 7:14, where ἀλήθεια inside the phrase ἡ καύχησις ἡμῶν ἡ ἐπὶ Τίτου ἀλήθεια ἐγενήθη is anarthrous, as the second instance of the article ἡ is pronomial.
All this information is already present in the SBLGNT, where article type is marked as "attributive", "pronomial", etc. We just need to be able to filter by that information to improve accuracy when searching for anarthrous or arthrous nouns.
