The article looks at Latin phrases still used in English, from a phrase that narrows what someone means to expressions for listing examples, describing good faith, and exchanging something in return. The lesson favors plain-English explanations where a Latin expression could obscure the point.

Cultural note: “Caveat emptor” is a legal and commercial maxim, not a substitute for current consumer-protection rules or legal advice. “Quid pro quo” simply describes an exchange in ordinary contexts; it does not, by itself, prove wrongdoing.

Keep exploringLatin can make a phrase sound polished, but clarity still matters more than sounding formal.

Precision and lists

Narrow a statement or shorten a list of similar examples.

per se

Meaning

By itself or considered separately from other things.

Tone & use

Often used to clarify that a specific part is not the main issue; plain English may be clearer for a general audience.

Example

“The schedule is not difficult per se; the problem is that it changes without notice.”

NeutralFormal / Latin phrase

et cetera (etc.)

Meaning

And other similar things; and so on.

Tone & use

Use it when omitted items are clear and similar to those already named. Do not use it to hide important details.

Example

“Please bring a notebook, a pen, a charger, et cetera—anything you need to take notes.”

NeutralNeutral / formal

Good faith and exchange

Describe an honest agreement or something given in return.

Recognition caution

caveat emptor

Meaning

“Let the buyer beware”; a warning that a buyer should check a product or deal carefully.

Tone & use

A traditional legal and commercial maxim. It is not a complete statement of current law or a replacement for consumer protections.

Example

“The used-bike listing urged buyers to inspect the frame before paying, echoing caveat emptor.”

NeutralFormal / legal

Not legal advice and not a claim that sellers have no obligations.

bona fide

Meaning

Genuine, sincere, or made in good faith.

Tone & use

Used in formal and everyday contexts, often before a noun such as “offer” or “expert.”

Example

“The group accepted a bona fide offer from a local artist to donate materials.”

PositiveFormal / Latin phrase

Recognition caution

quid pro quo

Meaning

Something given or done in return for something else.

Tone & use

Can describe ordinary reciprocal arrangements. In legal or political discussion, the context matters; the phrase alone does not establish misconduct.

Example

“The two clubs arranged a fair quid pro quo: each would lend equipment for one weekend.”

NeutralFormal / Latin phrase

Do not treat the phrase alone as evidence of an improper exchange.
