Function is a safer starting point than surface similarity
If an English Frame is used to soften disagreement, the useful question is not “which German or Russian words replace these English words?” It is “how is this communicative job naturally performed in the other language?” Sometimes the answer is structurally similar. Sometimes it is not.
A Move provides the language-independent anchor. Frames remain language-specific, and the Bridge records a reviewed relationship between them.
A Bridge can include asymmetry
Two Frames may overlap in one context but diverge in another. One can sound more formal, more direct or less common. A useful Bridge should preserve those differences instead of flattening them into an equals sign.
This is why Metkagram avoids generating cross-language relations automatically from translation fields. Translation can suggest a candidate; editorial review decides whether the functional correspondence is strong enough to publish.
Bridges support transfer without teaching translation dependence
For a learner, a Bridge can start from a familiar Move, then show how another language realises it. The learner gets a conceptual foothold without being told to translate every future sentence through the first language.
The long-term goal is independent retrieval: situation → Move → language-specific Frame. The Bridge helps build that path, but it should eventually stop being a required intermediate step.
