When you want to say that something was learned, seen, or experienced directly, you may wonder whether to write first hand, first-hand, or firsthand. All three forms can appear in English, but they do not have the same level of use or style.

This question often appears in writing about firsthand experience, firsthand knowledge, first-hand accounts, and direct evidence. The confusion comes from the way English turns word combinations into compounds. Over time, many compounds move from two words to a hyphenated form and then to one word.

Today, firsthand is a standard dictionary form, especially in American English. Cambridge lists firsthand as both an adjective and an adverb. Oxford, however, lists first-hand as an adjective and adverb. (Cambridge Dictionary)

So, which spelling should you use? The answer depends partly on your audience and style guide. This guide explains the difference in simple terms, gives useful examples, compares British and American usage, and shows when each form works best.

First Hand or Firsthand : Quick Answer

Firsthand and first-hand have the same basic meaning: directly experienced, observed, or obtained from the original source.

Examples:

• She has firsthand experience of teaching.
• She saw the accident firsthand.
• We received first-hand information from the witness.
• He learned about the problem at first hand.

Cambridge uses firsthand as both an adjective and an adverb. It defines the word as something experienced or obtained directly. (Cambridge Dictionary)

Oxford uses first-hand in its dictionary entries, including examples such as “first-hand experience.” (Oxford Learner’s Dictionaries)

Quick rule

Form	Meaning	Common use
firsthand	Directly or personally	Very common in American English
first-hand	Directly or personally	Common in British English and traditional usage
first hand	Directly	Usually in phrases such as “at first hand”

Best simple answer: Use firsthand as one word in most modern American English writing. Use first-hand if you follow a British style that prefers the hyphen.

The Origin of First Hand or Firsthand

The expression comes from the ordinary meanings of first and hand.

The word first refers to something at the beginning or original position. Hand has long been used in English to describe a person who handles, gives, receives, or works with something.

Together, the idea of first hand developed to mean information or experience that comes directly from the original source.

Dictionary.com dates the first recorded use of firsthand to around 1690–1700 and gives its formation as first + hand. (Dictionary.com)

The word later appeared in different written forms:

• first hand
• first-hand
• firsthand

English often changes compounds in this way. A phrase may begin as separate words, gain a hyphen, and eventually become one word.

The meaning has remained stable. If you see something yourself, hear it directly from someone involved, or experience it personally, you have experienced it firsthand.

British English vs American English Spelling

The main difference is style and dictionary preference, not meaning.

American English

American English commonly uses firsthand as one word.

Examples:

• firsthand experience
• firsthand knowledge
• firsthand evidence
• firsthand account
• I saw it firsthand.

Cambridge’s American Dictionary gives firsthand as an adjective and adverb. (Cambridge Dictionary)

British English

British English commonly uses first-hand, especially in traditional and formal writing.

Examples:

• first-hand experience
• first-hand knowledge
• first-hand evidence
• first-hand account
• I saw it first-hand.

Oxford lists first-hand as both an adjective and an adverb. (Oxford Learner’s Dictionaries)

Comparison table

Feature	American English	British English
Preferred common form	firsthand	first-hand
Adjective	firsthand experience	first-hand experience
Adverb	saw it firsthand	saw it first-hand
Meaning	Direct or personal	Direct or personal
Hyphen	Often omitted	Often retained
Alternative phrase	at first hand	at first hand

This difference does not mean that one form is wrong. Major dictionaries recognize the forms differently according to their editorial conventions. Collins also records firsthand, first-hand, and the phrase at first hand. (Collins Dictionary)

Which Spelling Should You Use?

Your audience should guide your choice.

For American English

Use firsthand as one word.

The researcher collected firsthand data.

This form fits common American dictionary usage and modern American prose. (Cambridge Dictionary)

For British English

Use first-hand if your publication or style guide follows the traditional British form.

The researcher collected first-hand data.

Oxford uses this form in its entries. (Oxford Learner’s Dictionaries)

For Commonwealth English

Usage can vary by country, publisher, and style guide. If you write for a specific publication, follow its house style.

For global websites

If your website targets an international audience, firsthand is a simple modern choice. More important than choosing between the two forms is using one spelling consistently.

For SEO, you can naturally mention both forms because readers may search for first hand or firsthand, first-hand or firsthand, and similar spelling questions.

Common Mistakes with First Hand or Firsthand

1. Using “first hand” everywhere

Incorrect in many contexts:

She has first hand experience.

Better:

She has firsthand experience.

Or:

She has first-hand experience.

The two-word form usually needs a specific construction, such as at first hand. Collins lists “at first hand” as a phrase meaning directly or personally. (Collins Dictionary)

2. Mixing styles

Avoid changing forms without a reason:

He gave firsthand information and a first-hand account.

This is not necessarily grammatically wrong, but consistency improves professional writing.

3. Assuming “firsthand” is only an adjective

It can also work as an adverb.

She experienced the event firsthand.

Cambridge lists both adjective and adverb uses. (Cambridge Dictionary)

4. Confusing firsthand with secondhand

Firsthand means direct or personal.

Secondhand means received indirectly from another source.

Compare:

I saw the event firsthand.

I heard about the event secondhand.

5. Adding an unnecessary hyphen

In American English, modern writing often uses firsthand rather than first-hand.

However, if your chosen style guide prefers the hyphen, use it consistently.

First Hand or Firsthand :  Google Trends & Usage Data

They can help compare search interest by country, time period, and search term. Google explains that Trends uses aggregated, anonymized search data and lets users examine interest over time and by geographic area. (Google for Developers)

However, Google Trends does not provide a permanent search-volume number for a word. Its values are relative to the selected time, location, and search settings. Google also recommends comparing terms and countries separately because search behavior can vary by location. (Google for Developers)

For this spelling question, the useful comparison is:

• firsthand — especially common in American English.
• first-hand — strongly represented in British and traditional dictionary usage.
• first hand — more restricted and often appears in the phrase at first hand.

Dictionary evidence supports this regional difference. Cambridge’s current entries use firsthand, while Oxford’s entries use first-hand. (Cambridge Dictionary)

Collins also records all three forms and shows related expressions such as first-hand experience, first-hand evidence, and first-hand information. (Collins Dictionary)

For SEO research, compare the exact phrases in Google Trends rather than assuming that one spelling represents all searches. Google notes that spelling variations can be treated separately when searching terms. (Google for Developers)
