3. changes  In some cases initial /s/ might be dropped. This is, however, mainly limited to three words, i.e. sudah, sama, and saja that regularly become udah, ama, and aja in C.I.  In proper Betawi Malay final /a/ also changes to /e/ rendering ama to ame, and aja to aje. This, however, is mainly restricted to 'true' Betawi Malay, and only occasionally found in C.I.
