Eh ( or ) is a spoken interjection in English that is similar in meaning to "Excuse me?," "Please repeat that", or "huh?". It is also commonly used as a question tag, i.e., method for inciting a reply, as in "It's nice here, eh?" In North America, it is most commonly associated with Canada and Canadian English, and with Michigan's Upper Peninsula. Similar interjections exist in other languages, such as Dutch, Armenian, Hokkien Chinese, Japanese, French, Finnish, Italian, Greek, Hebrew, Malay, Spanish, Persian, Portuguese, Arabic, Turkish, Korean and Catalan.

Western Sahara is a disputed territory, and as such it has no country code top-level domain (ccTLD). .eh is reserved for this purpose, and will be assigned if the Western Sahara conflict results in an agreement between Morocco and armies in the territory. IANA has no sponsoring organizations assigned to this domain.
