From Middle High German bloc, from Old High German bloc. The more common form was originally Middle High German bloch, Old High German bloh. The variant prevailed in modern German under the reinforcing influence of Middle Low German block. The architectural sense is loaned from English (and may therefore take a plural in -s).
- The normal plural is Blöcke.
- The plural Blocks is often, but not necessarily, used for sense 3 (“large building”).
