Breached is correct when you mean something was broken, violated, entered, or broken through.
Breeched is a real word, but it is rare. It usually means “wearing breeches,” or it appears in older writing about dressing someone in breeches. In some medical wording, it may describe a baby delivered or positioned breech, but breech is much more common than breeched in that setting.
So, in most modern US writing, the word you want is breached.
Quick Answer
Use breached for contracts, rules, trust, walls, accounts, systems, and security.
Use breeched only when you mean wearing breeches or, in limited context, born or delivered breech.
Correct:
The company breached the contract.
Incorrect:
The company breeched the contract.
Correct:
The rider was breeched for the historical reenactment.
That second sentence is possible, but it sounds old-fashioned and unusual. Most writers will almost never need it.
Why People Confuse Them
Breeched and breached look almost the same. They also sound the same in normal speech: breecht.
That makes the mistake easy to miss. You may hear “breached security” and picture either spelling. But the spelling changes the meaning.
The key difference is simple:
• Breached connects to breach, meaning a break, violation, gap, or breakthrough.
• Breeched connects to breech or breeches, meaning the rear part, a certain birth position, the back part of a firearm, or old-style pants.

Meaning and Usage Difference
Breached is the past tense and past participle of breach.
It means someone or something broke a rule, crossed a limit, opened a gap, or got through a barrier.
Examples:
The vendor breached the agreement.
The storm surge breached the seawall.
The account was breached last night.
He breached her trust.
Breeched is much narrower. As an adjective, it can mean wearing breeches. As a verb form, it can mean dressed someone in breeches, especially in older or historical use.
Examples:
The actor was breeched for the period costume.
In the old family record, the child was breeched at five.
For childbirth, the usual modern wording is breech baby, breech position, or breech delivery. You may see born breech or delivered breech more often than breeched.
Tone, Context, and Formality
Breached sounds normal in legal, business, news, privacy, and security writing. It can be formal, but it is also common in everyday language.
A landlord can breach a lease.
A worker can breach policy.
A wall can be breached.
An account can be breached.
Breeched sounds rare, old-fashioned, or highly context-specific. In everyday writing, it may look like a typo unless the sentence clearly involves breeches, historical clothing, or a breech birth context.
The pronunciation does not help much because the words sound alike. In writing, meaning is the guide.
Which One Should You Use?
Choose breached when the idea is “broke,” “violated,” “failed to follow,” “entered without permission,” or “broke through.”
Choose breeched only when the idea is tied to breeches or a clear breech context.
Compact comparison:
• Breached: contracts, rules, laws, trust, privacy, walls, banks, borders, accounts, systems.
• Breeched: wearing breeches; dressed in breeches; rare wording tied to breech position or birth.
• Most common choice: breached.
• Most common mistake: using breeched when you mean breached.
