Because of sound changes which took place over portions of the
Cebuano-speaking areas but did not spread over the entire area and the
subsequent spread of forms which reflect these changes, there are
numerous competing forms which are of the same etymology and which
usually (but not always) have the same meaning. [18]
Forms which are the same in meaning and which are related to each other
in that one underwent the sound change and the other did not are
defined only once and cross reference is made. Some sound changes are
so common and regular that only the older form is listed, and it is to
be taken for granted that the form which shows the sound change also
normally occurs unless a statement to the contrary is made.
