Maldives have a very strict way to deal with missionaries: If a missionary is detected, he will be immediately sent home. So there is quite an exchange of missionaries. So new missionaries have to be prepared for their service. For several missionaries from different continents, Johanna Mission wrote this little grammar of the Maldivian language:
Dhivehi Lessons (pdf)A dictionary has not yet been necessary, as there had been one available in the web. So Johanna Maldives only has a dictionary for the preparation of german missionaries. As the english dictionary has disappeared from the web, Johanna Maldives is preparing a dictionary Dhivehi-English (which will take some time).
Johanna Mission also made some pictures with biblical texts in Maldivian.
