My Imagination

There were many similarities in the names of places in Sabah, then North Borneo or North Kalimantan and that of Java especially west Java, where lies the port of Cirebon and the Cirebon Sultanate.

For example in Sabah he have places like;
Sipitang
Sikuati
Sibuga
Sibatik
Sisipit
Simunul
Sibuku
Sibutu
SiAmil

In Java we have places like'
Cirebon,
Cianjur,
Cipanas,
Ciawei,
Cinkareng (which was just hit by the powerful earthquke) and many others.

The difference is only in the letters but the sound quite similar. As was mentioned earlier people in the past went by the sound and not the words of everything as they had not formal education then.

There had been some twinning or it could have been the same person responsible for those names.
