Type–token distinction  The type–token distinction is the difference between naming a "class" (type) of objects and naming the individual "instances" (tokens) of that class. Since each type may be represented by multiple tokens, there are generally more tokens than types of an object. For example, the sentence "A rose is a rose is a rose" contains three word types, "a", "rose", and "is"; and eight word tokens of those types, "a", "rose", "is", "a", "rose", "is", "a", "rose". The distinction is important in disciplines such as logic, linguistics, metalogic, typography, and computer programming. The sentence ""they drive the same car"" is ambiguous. Do they drive the same "type" of car (the same model) or the same instance of a car type (a single vehicle)? Clarity requires us to distinguish words that represent abstract types from words that represent objects that embody or exemplify types. The type–token distinction separates types (abstract descriptive concepts) from tokens (objects that instantiate concepts). For example: "bicycle" represents a type: the concept of a bicycle; whereas "my bicycle" represents a token of that type: an object that instantiates that type. In the sentence "the bicycle is becoming more popular" the word "bicycle" represents a type that is a concept; whereas in the sentence "the bicycle is in the garage" the word "bicycle" represents a token: a particular object. The words type, concept, property, quality, feature and attribute (all used in describing things) tend to be used with different verbs. Suppose a rose bush is defined as a plant that is "thorny", "flowering" and "bushy". You might say a rose bush "instantiates" these three types, or "embodies" these three concepts, or "exhibits" these three properties, or "possesses" these three qualities, features or attributes. Property types (e.g. "height in metres" or "thorny") are often understood ontologically as concepts. Property instances (e.g. height = 1.74) are sometimes understood as measured values, and sometimes understood as sensations or observations of reality. Some types exist as descriptions of objects, but not as tangible physical objects. One can show someone a particular bicycle, but cannot show someone, explicitly, the type "bicycle", as in ""the bicycle" is popular.".
