While written APL is mostly symbolic, facilitating communication of thought across human language barriers, instructional text and verbal conveying of APL subjects requires human language translations of the glyphs and primitives etc. This article attempts to provide a standard for German terminology used in such contexts, to ease the burden of translators, assist speakers, and in general lessen the risk of misunderstandings in conversation.

At the 2020 APL Germany meeting, Michael Baas described the motivation behind a German terminology standard and launched a survey to measure the importance of this.[1] APL Germany subsequently published an article detailing this.[2]


This list is incomplete. Please edit this page to contribute, keeping the list in alphabetical order by primary English term. The primary English term is the corresponding article name (which should be linked) if an article exists. Use the Discussion page to remark about translations you disagree with, or to provide suggestions for otherwise improving this page. When a translation has historical or external precedent, please add a reference to that.
