hochparallele
Hochparallele is not a standard or widely recognized term in German technical vocabulary. There is no agreed-upon definition in major dictionaries or reference works, and its meaning is not fixed outside a specific context. The word can be read as a compound of hoch- (high) and parallele (parallel), which might suggest a relation of parallel elements located at a higher position, but such a usage is not established.
In practical texts, if the term appears, it is usually either a typographical variant or a coinage
Related and more established terms include Hochparterre (the architectural concept), Parallele (parallel), and Parallelogram (in geometry).
