Language Pair

A language pair refers to the combination of the source language and the target language in a translation project. For example, English to Mandarin is one language pair, and Mandarin to English is a different language pair. The concept is fundamental to how translation services are scoped, priced, and resourced.

Language pairs matter because translation is not a symmetrical process. A translator who excels at translating from English into Japanese may not be equally skilled at translating from Japanese into English. Professional translators typically work into their native language (the language they are most fluent in), which means the direction of the language pair determines which translators are assigned to a project.

Some language pairs are more common than others, with greater availability of qualified translators and established terminology resources. English to and from major world languages like Spanish, Mandarin, Arabic, and French are well-served, while less common pairs (such as Finnish to Vietnamese) may have limited translator availability and require more careful resourcing.

Pricing can vary significantly between language pairs based on translator availability, market demand, and the complexity of the language combination. Languages with different scripts, complex grammar systems, or significant text expansion typically carry higher per-word rates.

LEXIGO supports translation across 171 languages, covering both common and rare language pairs. Our global translator network ensures access to qualified linguists even for less common language combinations.

Understanding language pairs helps organisations plan translation projects more effectively. Knowing that some language pairs have limited translator availability or longer turnaround times enables better project planning. Understanding that pricing varies by language pair supports more accurate budgeting for multilingual programmes.

For procurement professionals, specifying language pairs rather than just listing target languages ensures that translation providers can accurately assess their capacity, timeline, and pricing for each project.
