The source text is the original language content that a translator or localization team receives as input before any target-language version is produced. In typical project handoffs and CAT tool workflows it appears as the left-side column of a segment pair, and translators, reviewers, terminologists, and query sheets all rely on the source text as the primary reference for meaning, constraints, audience, and intent.
In translation and localization work, the source text appears in authoring files, content management system exports, and the source column of translation memory tools. Translators and reviewers consult it when adapting UI strings, marketing copy, help content, or subtitles, and it anchors terminology extraction, query creation, and quality checks against the original intent.
A common error is treating a source text as context-free strings, especially when it is ambiguous, contains idioms, or uses placeholder syntax. Translators who translate word-for-word without seeing the source in the UI may produce a target text that is fluent locally but breaks function, tone, or layout, leading to costly rework.
For creative and consumer content the failure mode is flatness, not inaccuracy — and flatness passes an accuracy check. Terms here also carry technical constraints (reading speed, character budgets) that are part of the brief.
Angel Translation locks terms like this into a project terminology base before expert review begins, so the same source term resolves to the same target term across every document in a submission — and stays consistent in the next revision. See the 8-step AI + expert workflow.
