Code:
SELECT id.id, DISTINCT id.keyword, en.translation AS en_translation, de.translation AS de_translation FROM i18n AS id LEFT JOIN i18n AS en ON id.keyword = en.keyword LEFT JOIN i18n AS de ON id.keyword = de.keyword ORDER BY id.id ASC
Zu der anderen Frage: lasse die "WHERE"-Bedingung mal ganz weg.
