What Must Survive Translation?

Translation is not only the replacement of one set of words with another.

A technically accurate sentence can still fail if the distinction, instruction, joke, relationship, or effect carried by the original no longer works.

This is especially clear with ideas whose value depends on what they let a reader notice or do.

The question becomes functional.

What must survive the crossing?

Terminology may change.

Syntax will change.

Cultural references may need replacement.

Examples that are obvious in one setting may become confusing in another.

Yet something has to remain recognizable enough that the idea can still perform its work.

This is where attribution and adaptation meet.

A translator should not erase the source merely because literal wording has changed.

Nor should fidelity require preserving wording that prevents the idea from being understood.

The same problem appears outside human languages.

An idea moves from speech to writing, from a classroom to an online course, from expert vocabulary to public language, or from a human explanation to an AI-assisted summary.

Each medium can preserve some things and distort others.

Good translation therefore asks more than 'Is this sentence equivalent?'

It asks: can the reader still encounter the distinction the sentence was carrying?

Words cross the boundary.

The work of the words has to cross with them.
