Among these things; in the midst of this group or situation (archaic).
Compound of here (Old English her) and among (from Old English on-gemang, meaning 'in a crowd' or 'mixed together'). This represents the archaic practice of combining here with prepositions to denote spatial or situational relationships.
Medieval writers used 'hereamong,' 'therein,' and similar forms as elegant ways to refer back to previously mentioned things without repetition—a linguistic efficiency tool that modern English replaced with clearer but wordier constructions.
