I am trying to find all of the Aramaic loanwords that appear in the Hebrew Bible. Thus far, I can only find Aramaic words that appear in text that has been designated as Aramaic text, but I want to find Aramaic words that appear in Hebrew text. A test case is רעיון (Eccl 2:22), which HALOT identifies as an Aramaic loanword. I would think that searching for any Aramaic noun using the syntax morph.sesb.a:N????+S in BHS should retrieve every Aramaic lexeme in the Hebrew Bible regardless of whether it appears in a portion of text designated as Hebrew or a portion of text designated as Aramaic, including רעיון in Ecclesiastes 2:22. The results, however, utterly lack any portion of text that is not designated as Aramaic. No Aramaic lexemes outside of Aramaic portions appear in the results.
How can I find all the Aramaic loanwords in the Hebrew Bible?
