Secondclass

Secondclass, often written as second class or second-class, is a term used to describe a category or status considered inferior to a corresponding first-class counterpart. It is applied in several domains, with meanings that depend on context, country, and historical period. The concept generally signals a tiered system where resources, rights, or privileges are distributed unequally.

In social and political contexts, “second-class” describes groups or individuals who lack full rights or protections compared with the majority or with a “first-class” group. The term is commonly associated with discussions of discrimination, unequal treatment, and civil rights, and it is frequently debated in debates over equality and inclusion.

In transportation, second class refers to cheaper, more basic travel accommodations relative to a higher tier such as first class. This can include trains, airplanes, or buses, where service levels, seating, and amenities are typically more limited. In many regions, the terminology has evolved, with operators replacing rigid first/second distinctions with terms like economy or standard, yet the underlying idea of a lower tier persists in some markets.

In postal services, second-class mail denotes a cheaper, slower category of mailing than first-class services. The specifics—rates, delivery times, and eligibility—vary by country and postal system. Some countries continue to operate distinct first-class and second-class options, while others have merged or renamed these classes.

In education, the term is used in degree classifications in some countries. For example, in certain systems a second-class honours degree indicates a lower subdivision (such as 2:2) within the honours framework, with broader variations across institutions and jurisdictions.

In computing and theoretical discussions, “second-class citizens” describe entities that are not fully first-class and thus have limited capabilities or expressiveness within a language or system. Examples and implications differ by programming language and paradigm.
