heart broken (heartbroken)

"Heartbroken" is one word when it describes deep sadness. Writing "heart broken" looks like a noun plus a participle and is nonstandard in modern prose.

Below are concise rules, clear examples, context-appropriate rewrites (work, school, casual), hyphenation and spacing notes, memory tricks, and similar errors to watch for.

Quick answer

Use heartbroken as one word to mean "deeply sad" or "emotionally devastated." Don't split it into "heart broken." Use "heart-broken" only as a deliberate poetic or archaic choice.

"She felt heartbroken." - correct.
"She felt heart broken." - incorrect in standard prose.
For formal tone, consider synonyms like devastated, distraught, or deeply upset.

Core explanation: adjective vs noun + participle

Heartbroken is a closed compound adjective: it answers How did she feel? and follows linking verbs (feel, seem, be).

Splitting it into "heart broken" invites a noun + past participle parse (heart + broken), which disrupts the expected adjective pattern and feels awkward.

Use the closed form for states and emotions: She seemed heartbroken.
The closed form also modifies nouns directly: a heartbroken letter.

Wrong: She felt heart broken when she got the news.
Right: She felt heartbroken when she got the news.

Hyphenation and spacing: when (if ever) to hyphenate

Modern dictionaries list heartbroken as one word. A hyphenated form (heart-broken) is a stylistic, poetic, or historical choice rather than standard prose.

Accidental splits can come from line breaks or poor copy-paste; these create "heart broken" errors that you should correct.

Prefer heartbroken; use heart-broken only for deliberate archaic or poetic effect.
Check house style: some guides hyphenate before nouns, but most don't require a hyphen here.
Search your document for the two-word sequence "heart broken" to catch spacing mistakes.

Poetic: The heart-broken wanderer sang at dusk. (deliberate style)
Spacing error: At the line break she was heart broken. → Fix: heartbroken.

Real usage: work, school, casual

Choose wording that fits the register. For formal reports or emails, prefer a measured synonym; in creative or casual writing, heartbroken is fine.

Work (direct): She was heartbroken after we lost the contract.
Work (formal): The team was deeply upset after the contract loss.
Work (email): I'm sorry to report the client left us; several members are heartbroken by the outcome.
School (report): She appeared heartbroken after receiving her grades.
School (formal): She was distraught upon learning the exam results.
School (creative): The character returned home, heartbroken and silent.
Casual (text): I'm heartbroken - can't believe it's over.

Step 2: Read the sentence aloud. If there's an awkward pause, join the words.
Step 3: If the tone needs formality, replace with a synonym (devastated, distraught, deeply upset).

Memory trick and quick rules

Mnemonic: If it's an emotion coming from the heart, pack it together-heart + broken = heartbroken.

If the phrase answers "How?" or "How did they feel?" use one word.
Preserve original spelling in historical quotes; otherwise modernize to heartbroken.
