If a sign refers to an object well known already to utterer and interpreter, and gives neither party any latitude as to what it represents, it may be called a singular sign, or singular.

1904 | Foundations of Mathematics [R] | MS [R] 11:1

If a sign allows no latitude, either to utterer or to interpreter, as t what object or meaning it shall be regarded as representing, it may be called a singular sign.

1904 | Foundations of Mathematics [R] | MS [R] 9:2-3

…a sign cannot be at once vague and general in the same respect. It may, however, be both definite and individual; and in that case may be said to be used singularly. ‘Man’ is used vaguely in ‘Some man sins’; generally, in ‘Every man sins’; singularly, in ‘This man sins.’
