inbetween

Inbetween is a term used to describe a state or position that lies between two or more points, times, conditions, or categories. It can function as a noun (“the in-between”), an adjective (“an in-between phase”), or an adverb in phrases such as “to be in between.” The form “in-between” with a hyphen is common, while “in between” as two words is also standard. The single-word form “inbetween” is less common and mainly appears in branding or informal contexts.

Etymology and usage notes: Inbetween derives from in + between, a combination that has existed in English for centuries. The hyphenated form helps signal its role as a compound adjective; both hyphenated and open forms are accepted in contemporary writing, with preference often guided by house style or readability.

Applications and examples: In mathematics or measurement, an in-between value denotes an intermediate point on a scale. In time, it refers to the interval between events. In geography, architecture, and design, “in-between spaces” describe transitional zones such as hallways, foyers, or urban gaps that connect distinct areas. In everyday speech, one might refer to an “in-between job” or describe a person as being in between stages of life, training, or mood.

Related concepts and see also: The idea of inbetweenness overlaps with terms such as intermediary, intermediate, liminal, threshold, and transition. In cultural and philosophical contexts, the in-between is often treated as a space of possibility, ambiguity, or transformation rather than a fixed category.
