hoc

Hoc is a term used in several contexts, including classical Latin and modern technical fields. In Latin, hoc is the neuter singular demonstrative pronoun meaning "this" or "this thing," paired with masculine hic and feminine haec. It is used to point to something previously mentioned, to introduce a statement, or as a subject in clauses.

In Latin grammar, hoc declines as a neuter form of hic, haec; common phrases include Hoc est verum ("This is true") and Hoc ipsum ("This very thing"). Its usage is primarily literary or educational in modern contexts.

In Christian liturgy, the phrase Hoc est corpus meum is part of the Roman Catholic Mass and is used during the consecration, translated as "This is my body."

In modern computing and programming, HOC is an acronym for higher-order component, a pattern in component-based libraries such as React. A higher-order component is a function that takes a component and returns a new component, enabling reuse of logic and cross-cutting concerns like theming or state management.

The sequence hoc (lowercase) can also appear as part of words in many languages, and as an acronym in other domains. Because it is short and context-dependent, its meaning is determined by the surrounding text.
