Rain is wet is a singular statement.

It expresses the fact that rain (a proper name identifying the liquid which falls from the sky under certain meteorological conditions) has the property being-wet.

In the language of symbolic logic, this could be written as follows:

  • Let $\mathbf r$ be rain.
  • Let $W$ be the property being wet.

Thus we symbolize Rain is wet as $W \left({\mathbf r}\right)$.

$2 + 3 = 3 + 2$ is a singular statement.
