Source text for interfaces and documentation translates cleanly when sentences are complete units, strings are never assembled from fragments, plurals and placeholders go through the framework, and idioms, humour and culture-specific references are left out; the constraints come from how gettext-style tools and translators work.

What it is

Writing for translation means shaping the source language so that a translator, or a machine translation step, can produce a correct target text without asking the author and without the code fighting back. The GNU gettext manual (cited) lists the rules on the code side: decent English style, entire sentences, split at paragraphs, format strings instead of string concatenation, placeholders instead of embedded URLs. Its plural-forms page (cited) adds that counts must go through the plural function rather than a hand-built file%s, because languages have different numbers of plural forms; it shows languages with two, three and more forms and header rules such as nplurals=3. Google's style guidance for a global audience (cited) covers the prose side: consistent terminology and sentence structure, and omitting colloquialisms, idioms, humour and seasonal references.

Why it matters

Word order, gender, plural rules and sentence length differ between languages. A string built from fragments ("Deleted " + n + " file(s)") cannot be reordered or inflected by the translator; an English-only idiom either gets translated literally or replaced by a guess; a sentence that depends on an English pun has no target text at all. Every such case becomes a question to the author or a wrong translation in production.

How to apply

One string per complete sentence or label; never assemble a sentence from pieces at run time.
Use named placeholders ({count} files in {folder}) so the translator can reorder them; give translators a comment saying what each placeholder contains.
Route every count through the plural function of the framework, including the English source ("1 file", "2 files"); do not write "file(s)".
Keep terminology fixed: one term per concept, taken from the glossary, so the translation memory matches.
Prefer short declarative sentences with standard word order; avoid stacked nouns and ambiguous pronouns ("it", "this") whose referent is unclear.
Leave out idioms, humour, cultural and seasonal references, and examples that assume one country's formats; write dates, numbers and currencies through locale-aware formatting rather than in the string.
Leave room: a translation can be longer than the source, so layouts and column widths must not assume the source length.
Mark what must not be translated (product names, commands, code) in the source with the tool's mechanism.

Pitfalls

Reusing one string for two meanings ("Open" as a verb and as a state). Sentences split across interface elements. Screenshots with embedded English text. Changing source strings for cosmetic reasons, which invalidates every existing translation of that string.
