What is Internationalization (i18n)?

Engineering a product so it can be localized: externalized strings, flexible layouts, locale-aware formatting.

In more depth

In WordPress, i18n means gettext functions and translatable templates. Front-end translation tools sidestep much of it by translating rendered output.

Why it matters for your website

Understanding Internationalization (i18n) helps you make better decisions when taking a WordPress site multilingual — from choosing URL structures and engines to controlling costs. Transxlate handles the mechanics (language URLs, lang attributes, caching, hreflang on Pro) so terms like this become settings, not engineering projects.
