Number marking

Forming plurals in Sinhala is unpredictable. In Sinhala animate nouns, the plural is marked with -o(ː), a long consonant plus -u, or with -la(ː). Most inanimates mark the plural through disfixation. Loanwords from English mark the singular with ekə, and do not mark the plural. This can be interpreted as a singulative number.

On the left hand side of the table, plurals are longer than singulars. On the right hand side, it is the other way round, with the exception of paːrə "street". lexemes are mostly in the classes on the left-hand side, while lexemes are most often in the classes on the right hand.
