missing hyphen in '2 person meeting'

Missing hyphens can change meaning or make writing look unpolished. Below are clear rules, plenty of ready-to-copy corrections, quick rewrites, and memory tricks to stop repeating the same errors.

Quick answer

Hyphenate compound modifiers that come before a noun (a well-organized event), number+unit modifiers before a noun (a 10-hour meeting), and some prefix combinations that would otherwise confuse readers (re-enter). Don't hyphenate when the phrase follows the noun (the event was well organized) or for adverb + adjective pairs (highly qualified).

Before a noun? Usually hyphenate: a two-person team.
After the noun? Usually no hyphen: the team is two people.
Use hyphens to avoid misreading (re-sign vs resign).
Check a dictionary or your house style for words that have become closed (email) or open (high school).

Core rule: hyphenate compound modifiers before a noun

When two or more words together describe a noun and appear before it, link them with a hyphen so readers parse them as a single idea. If the same words follow the noun, you usually drop the hyphen because the relationship is clear from the sentence structure.

Before the noun = hyphenate: a well-organized plan.
After the noun = no hyphen: The plan was well organized.

Wrong: It was a well organized event.
Right: It was a well-organized event.
Wrong: She has a part time job.
Right: She has a part-time job.
Wrong: We met with a long term client yesterday.
Right: We met with a long-term client yesterday.

Numbers and units: hyphenate when used as modifiers

When a number and a unit together describe a noun, hyphenate: a 10-hour workshop, a six-month plan, a 20-year-old student. If the measurement follows the noun, no hyphen: The workshop lasted 10 hours. Spell numbers out in some contexts (six-month), but the key is consistency.

Hyphenate ages/durations before a noun: a 5-minute break, a 3-year warranty.
No hyphen when the phrase follows the noun: The intern is 20 years old.

Wrong: We scheduled a 10 hour meeting.
Right: We scheduled a 10-hour meeting.
Wrong: She is a 20 year old student.
Right: She is a 20-year-old student.
Wrong: Take a five minute break.
Right: Take a five-minute break.

Prefixes and clarity: when to hyphenate

Use hyphens with prefixes when they prevent misreading, avoid awkward double letters, or attach to a proper noun. Some prefixes are now closed (email), but many remain hyphenated for clarity (self-made).

Hyphenate to avoid collision: re-enter (enter again) vs recover (get better).
Prefix + proper noun: hyphenate (pre-World War II).
self- before a noun: self-made, self-employed.

Wrong: The self made chef opened a restaurant.
Right: The self-made chef opened a restaurant.
Wrong: We need to re enter the data.
Right: We need to re-enter the data.
Wrong: He is pro American in his views.
Right: He is pro-American in his views.

Hyphen vs en dash and spacing: technical but practical

Use a hyphen (-) to join words. Use an en dash (-) for ranges (2019-2020) or some complex compounds per style guides. Never add spaces around hyphens used to connect words. Use an em dash (-) for breaks in thought, not for linking words.

Hyphen: two-year-old. No spaces.
En dash: 2019-2020 (range) - style guides vary.
Em dash: use for breaks - not for linking words.

Wrong: She wrote a well - respected review.
Right: She wrote a well-respected review.
Usage: 2019-2020 season (en dash) vs 10-year contract (hyphen).

Real usage and tone: when you can relax the rule

Formal documents and academic writing favor strict hyphenation. Marketing copy and blogs sometimes prefer open compounds for readability. Pick a consistent approach per document and follow a dictionary or house style for edge cases.

Be consistent across a document or site.
Follow a dictionary for words that have evolved.
Use hyphens when ambiguity would hurt clarity (re-cover vs recover).

Usage: Many guides prefer email over e-mail, but self-made is still hyphenated.
Usage: high school student (open) but high-school-level exam (hyphen before noun).

Test the whole sentence rather than the isolated phrase-the surrounding words often make the right choice obvious.

How to fix your sentence right now: checklist and quick rewrites

Checklist: 1) Do two or more words jointly modify a noun? 2) Are they before that noun? 3) Is it number+unit as a modifier? 4) Could a prefix change meaning? If yes, hyphenate. If unsure, move the modifier after the noun or rephrase.

Option A: Add a hyphen: user-friendly interface.
Option B: Move modifier after the noun: The interface is user friendly.
Option C: Rephrase: We designed the interface for users.

Rewrite:
Wrong: We need a user friendly interface. -
Rewrite: We need a user-friendly interface.

Memory tricks and rules of thumb

Mnemonic: "Before the noun - bind with a hyphen." If a phrase answers "what kind of?" before a noun, hyphenate. Treat a number+unit as a single adjective when it precedes a noun.

Practical habits: keep a short personal list of words you always hyphenate, run a quick search for common patterns (part time, well known), and choose a dictionary or style guide for edge cases.

Say the modifier as one phrase-if it reads as a single idea, hyphenate.
Keep a cheat sheet: self-made, go-to, follow-up, long-term, part-time.
Search-and-fix: look for "part time", "two person", "well known" when proofreading.

Similar mistakes to watch for

Don't confuse hyphenation with adverb + adjective combos (no hyphen for highly qualified), compound nouns that follow dictionary convention (sister-in-law vs bus stop), or misuse of different dashes and spacing.

Avoid unnecessary hyphens that break closed compounds or add spaces around hyphens.

Adverb + adjective: no hyphen (a highly qualified candidate).
Compound nouns: check the dictionary (bus stop, toothpaste).
Dashes and spacing: don't use hyphens as em dashes or add spaces around them.

Wrong: A highly-qualified candidate applied.
Right: A highly qualified candidate applied.
Wrong: Please check the project - plan for issues.
Right: Please check the project plan for issues.
Wrong: Email us at support - [email protected].
Right: Email us at [email protected] (if the address uses a hyphen); do not add spaces around hyphens.

FAQ

Should I hyphenate compound adjectives before or after the noun?

Hyphenate when the compound adjective comes before the noun (a full-time job). When the same phrase follows the noun, drop the hyphen (The job is full time).

Is it 10-year-old student or 10 year old student?

Use hyphens when the age phrase modifies a noun before it: a 10-year-old student. If the age follows, write The student is 10 years old.

Do I hyphenate reenter or re-enter?

Hyphenate when needed to avoid misreading: re-enter (enter again). Some guides accept reenter, but a hyphen improves clarity in many contexts.

Why does "high school" sometimes have a hyphen and sometimes not?

As a noun, high school is open (She is a high-school student is also common in informal use). As an adjective before another noun, hyphenation improves clarity: high-school-level exam.

How do I tell if my prefix needs a hyphen (selfmade vs self-made)?

Self- compounds are usually hyphenated (self-made). For other prefixes, hyphenate to prevent ambiguity or awkward letter doubles (re-enter, pre-2010). When in doubt, consult your dictionary or house style and stay consistent.
