before hand (beforehand)

Short answer: write beforehand (one word). The two-word form before hand and the hyphenated before-hand are nonstandard when you mean "in advance."

Below: a concise grammar note, many ready-to-copy wrong/right pairs, quick rewrites, and practice sentences for work, school, and casual use.

Quick answer

Use beforehand (one word). It is an adverb meaning "in advance" or "earlier." Avoid "before hand" and "before-hand."

Correct: I finished the report beforehand.
Incorrect: I finished the report before hand.
If you prefer a phrase: use "in advance" or "ahead of time."

Core explanation: what beforehand means

Beforehand is a single-word adverb that answers when - it modifies verbs and means "in advance" or "earlier."

Writing it as two words makes "hand" look like a noun, which changes the meaning and breaks standard usage.

Part of speech: adverb.
Meaning: in advance; earlier; before something else.
Style: acceptable in formal and informal writing.

Wrong: Please prepare the materials before hand.
Right: Please prepare the materials beforehand.

Spacing and hyphenation: why not "before hand" or "before-hand"?

Dictionaries list beforehand as one word. Splitting or hyphenating it is nonstandard when you mean "in advance."

Prefer the single word or a clear rephrase like "in advance" or "ahead of time" for variety or rhythm.

Correct: beforehand
Incorrect: before hand, before-hand
If a spell-check suggests a hyphen, trust the dictionary or rephrase.

Wrong: They announced the policy before-hand.
Right: They announced the policy beforehand.

Real usage: formal, neutral, and casual examples

Beforehand fits most contexts. You can swap alternatives for tone or clarity, but don't split or hyphenate.

Formal: safe in reports and proposals.
Neutral: natural in emails and instructions.
Casual: fine in messages; "ahead of time" or "earlier" are also common.

Work - formal: Please submit your draft beforehand so the committee can review it.
Work-neutral: We need the figures beforehand to prepare the presentation.
Work - wrong: We need the figures before hand to prepare the presentation.
School-neutral: Read the article beforehand if you want to discuss it in class.
School - wrong: Read the article before hand if you want to discuss it in class.
Casual: Give me a heads-up beforehand if you can't make it.
Casual - wrong: Give me a heads-up before hand if you can't make it.
