The Hebrew word you mention, ishshash is actually rendered by those who study Scripture as ishshah (You have an extra "s" not needed) or issah -- which is the same word & the spelling I've been using. (The reason why ishshah is often used because that's how it sounds.)
And thank you for reminding us of the Gal. 4 passage describing Hagar as a bondwoman. (I suppose I could add Paul to my Q&A witnesses as a sixth person who describes her NOT as Abraham's extra wife, but only as a bondwoman!)
