Handling a Tricky Verb: Es handelt sich um "handeln"

Discussion of a difficult topic of German grammar: use of the V handeln 'to act'. This V, although very frequent, is listed incompletely in all major reference works. Examples & translations of 13 different major constructions with the V are offered, & suggestions are made on which ones should be included in German instruction at which level. Suggested levels are advanced German courses & courses in translation. Ample practice material for student use is appended. AA
