A singular term is a paradigmatic referring device in a language. Singular terms are defined as expressions that purport to denote or designate particular individual people, places, or other objects. They contrast with general terms (such as "car" or "chair") which can apply to more than one thing. [1]
In this table, The first cell in each row gives a symbol; The second is a link to the article that details that symbol, using its Unicode standard name or common alias.
One could define the x-axis as a tangent at this point, but this definition can not be the same as the definition at other points. In fact, in this case, the x -axis is a "double tangent." For affine and projective varieties , the singularities are the points where the Jacobian matrix has a rank which is lower than at other points of the variety.
While Kalaw Lagaw Ya has the singular-dual in all nouns, Central Pame has it specifically in inanimate nouns, such as čihàgŋ, spoon(s) (one or two), and šihàgŋ, spoons (plural, three or more). Pame animate nouns largely have a full three-way distinction: n adò , dog (singular); n adò i , two dogs (dual); and l adò t , dogs (plural).
A singular point of an implicit surface (in ) is a point of the surface where the implicit equation holds and the three partial derivatives of its defining function are all zero. Therefore, the singular points are the solutions of a system of four equations in three indeterminates. As most such systems have no solution, many surfaces do not ...
It was noticed in the formulation of Bézout's theorem that such singular points must be counted with multiplicity (2 for a double point, 3 for a cusp), in accounting for intersections of curves. It was then a short step to define the general notion of a singular point of an algebraic variety; that is, to allow higher dimensions.

A one-letter word is a word composed of a single letter. The application of this apparently simple definition is complex, due to the difficulty of defining the notions of word and letter. One-letter words have an uncertain status in language theory, dictionaries and social usage.
