When editing, I paused while reading and wondered why Inbetween or In Between feels like a difficult word to understand, as this small phrase raises a question about grammar rule, writing standards, and language convention in the English language today.
From a technical view, in-between is hyphenated as a compound adjective, shaped by hyphenation rule, punctuation style, syntax, morphology, semantics, and word formation, while in between stays two words in the English dictionary with proper word spacing.
This article offers answers, explanation, and reference through comparison, helping writers and readers avoid misspelling, confusion, and grammatical mistake, while improving clarity, correctness, accuracy, and professional writing confidence.
Understanding the Terms
What Does “In Between” Mean?
“In between” functions as a preposition or adjective. Essentially, it describes something that is in the middle of two objects, positions, or states.
Examples:
- “The vase sits in between the two books on the shelf.”
- “She felt lost in between happiness and sadness.”
It’s versatile. As a preposition, it shows a relationship between two points. As an adjective, it describes the middle state of something.
What About “Inbetween”?
“Inbetween” is often seen in informal contexts, such as social media captions, brand names, or artistic titles. However, standard English dictionaries and style guides mark it as incorrect.
Example of informal usage:
- “Check out my new blog, Inbetween Thoughts.”
Notice how this is a title, not a standard sentence. In formal writing, stick to “in between.”
Grammar and Usage Rules
When to Use “In Between”
Here’s a clear breakdown:
As a Preposition: Connects two objects or positions.

As an Adjective: Describes a state that is neither one thing nor another.
- “The painting depicts an in-between moment of day and night.”

Notice how hyphenation may appear when used as an adjective, especially in descriptive writing.

Informal Writing: Social media, casual notes, or creative titles sometimes see “inbetween”, but this is stylistic, not grammatical.

Exceptions and Misconceptions
- Hyphenation: “In-between” can appear with a hyphen when used adjectivally (“an in-between stage”), but never as a single word without the hyphen.

- Mistake 1: Writing inbetween as a single word in essays or reports.
- Mistake 2: Forgetting the hyphen when using in-between as an adjective.
- Mistake 3: Misplacing in between in sentences, which can make them confusing.
