Spoken by over two million people in the Special Region of Aceh, Acehnese is one of the major regional languages of Indonesia. A community of speakers is also found in Kedah, Malaysia. The Acehnese people have a highly developed literary tradition, and a rich history. This is the only published lexicon which supports translation into Acehnese - previous Acehnese dictionaries have been Acehnese-Dutch or Acehnese-Indonesian. The Thesaurus is a valuable tool for language learners and for others such as health professionals or agricultural consultants working amongst Acehnese people.
