Disabilities registration book

The sign for “Disabilities registration book” that is widely used among the Thai deaf is a combination of the signs

[ [book] [stamp] [blue] ] . This sign is ambiguous as it can be interpreted either as:

1. A book which was stamped with blue ink.

2. A book with a blue cover which was already stamped.

The sign that communicates more clearly is a compound of [ [book] [disabilities] [stamp] ] .

It gives the meaning of a book which was stamped with a seal of disabilities.

The sign [stamp] may also mean [register].
