I will, as an exercise, present ids for German prefixes/prepositions–ent-, er-, um-, an-, ab-, zer-, etc. It will be a way for me to gain clarity on the meanings of terms beginning with them.
I’ll start with zer-. I think my id for it is very effective–I LIKE IT! I like what I am doing. Having ids — graphic images–for the terms will help them stick in my mind.
