Decide Whether to Treat Borrowed Words as Single Units
English incorporates hundreds of terms borrowed from French, Latin, and other languages over centuries of trade, diplomacy, and scholarship. When you meet an unfamiliar borrowed expression in a sentence, treat the words together as one fixed vocabulary item rather than translating individual components. Word by word translations usually produce misleading literal definitions that obscure the actual meaning accepted in modern workplace English.
-
The policy is not unfair per se, but it needs clearer wording.
Why it works: Per se functions as a fixed unit meaning in itself, modifying the adjective unfair.
Your turn
Why should you avoid translating borrowed phrases word by word?
Answer: Literal translations often hide the established meaning accepted in modern English.

Answer: Literal translations often hide the established meaning accepted in modern English.
Borrowed terms function as single lexical units in English, so literal translation produces inaccurate meanings.
Choose Ad Hoc for Single Purpose Solutions
Use the Latin phrase ad hoc when an action, committee, or procedure exists solely to solve a specific, immediate problem. Many learners confuse ad hoc with rushed or careless, but an ad hoc group can work very methodically. The defining feature is purpose: standard procedures apply broadly across time, whereas an ad hoc process dissolves once its specific assignment concludes.
-
The hospital formed an ad hoc task force to manage the power outage.
Why it works: Ad hoc indicates the task force exists specifically for the emergency outage.

Which situation best represents an ad hoc arrangement?
Answer: A temporary working group formed to resolve one specific software bug.
Show the answer
Answer: A temporary working group formed to resolve one specific software bug.
Ad hoc arrangements are created for a specific single purpose rather than ongoing operations.
Distinguish De Facto Realities from Formal Titles
De facto describes a condition that functions in actual daily life regardless of whether legal statutes or company charts officially acknowledge it. Contrast de facto with de jure, which refers to official legal authority. In many offices, an experienced employee acts as the de facto supervisor by guiding junior staff daily, even though another person officially holds the management title on paper.
-
Although the contract named David as director, Sarah was the de facto leader.
Why it works: De facto highlights that Sarah directed daily operations in reality, despite David holding the title.
Your turn
What does calling someone a de facto team leader imply?
Answer: The person actually directs the team in practice without formal appointment.
Show the answer
Answer: The person actually directs the team in practice without formal appointment.
De facto indicates that a situation exists in reality even if it is not formally documented.
Separate Déjà Vu from Genuine Memories
Borrowed directly from French, the phrase déjà vu translates literally as already seen. In English conversation and psychological writing, it describes the unsettling sensation that a novel experience has previously occurred. You should never use déjà vu when referring to a verifiable factual memory. If you can date and prove the previous event, call it a recollection or a previous visit.
-
Entering the quiet lobby gave Marcus a sudden wave of déjà vu.
Why it works: Déjà vu specifies an intuitive sensation of familiarity without evidence of an earlier visit.
Your turn
When should a speaker use the term déjà vu?
Answer: When experiencing an unverified sensation that a new situation happened before.
Show the answer
Answer: When experiencing an unverified sensation that a new situation happened before.
Déjà vu describes a psychological feeling of repetition rather than a verifiable memory.
Identify a Faux Pas in Social Etiquette
A faux pas is an unintentional social blunder that breaches unwritten community norms or professional etiquette. The French expression means false step. Unlike a legal violation or technical error, a faux pas involves social awkwardness, such as asking a personal question during an initial job interview or showing up in casual clothes to a black tie banquet.
-
Calling the senior client by an informal nickname was a noticeable faux pas.
Why it works: Faux pas denotes a breach of professional etiquette that creates social unease.
Your turn
Which event is the clearest example of a faux pas?
Answer: Asking a client private financial questions during a friendly dinner.
Show the answer
Answer: Asking a client private financial questions during a friendly dinner.
A faux pas is a social or etiquette misstep, not an arithmetic error or travel delay.
Reserve Per Se for Formal Analytical Contexts
The Latin phrase per se means by itself or intrinsically. Professional speakers use it most frequently after negative statements to isolate one specific quality from related consequences. For instance, stating that a budget is not small per se means the funding level is acceptable, even if the timeline poses severe logistical challenges. Avoid using per se merely as decorative conversational filler.
-
The software upgrade is not complicated per se, but staff need time to adapt.
Why it works: Per se shows that the software itself is straightforward, even though staff training requires time.
Your turn
What does a speaker mean by saying a proposal is not flawed per se?
Answer: The core proposal itself is sound, even if related circumstances create issues.
Show the answer
Answer: The core proposal itself is sound, even if related circumstances create issues.
Per se isolates the core object itself from external factors or surrounding difficulties.
Replace Borrowed Phrases with Direct Alternatives
While borrowed phrases carry exact legal or literary histories, they frequently create comprehension barriers for international clients, general customers, or junior colleagues. You communicate with greater authority when you choose clear Anglo-Saxon or common international English terms. Instead of ad hoc, write temporary or specialized; instead of de facto, write practical; instead of faux pas, write social error.
-
We introduced a temporary solution while engineers repaired the water pipe.
Why it works: Temporary solution communicates immediate meaning faster than ad hoc arrangement.
Your turn
Which plain English phrase best replaces ad hoc in customer documentation?
Answer: Specialized for this case
Show the answer
Answer: Specialized for this case
Specialized for this case conveys the single purpose meaning of ad hoc without Latin jargon.
Evaluate Audience Knowledge Before Hitting Send
Before sending an email or report containing borrowed phrases, evaluate who will read the text. In academic papers, legal briefs, and executive memos, terms such as de facto and per se are standard shorthand that peers respect. In public notices, onboarding manuals, and cross-border team chats, simpler alternatives protect your message against misinterpretation and unnecessary reading delays.
-
The company handbook explains official policies in straightforward English.
Why it works: Straightforward English ensures all employees understand rules without translating Latin terms.
Your turn
When is retaining a borrowed Latin phrase most appropriate?
Answer: When writing a formal legal brief intended for experienced attorneys.

Answer: When writing a formal legal brief intended for experienced attorneys.
Specialized audiences such as attorneys expect standard Latin terms and understand them instantly.
Before you go
Remember this
Borrowed phrases add nuance to specialized writing, but they create confusion when readers do not know their Latin or French roots. Use ad hoc for single-situation solutions, de facto for unwritten realities, déjà vu for false familiarity, faux pas for social mistakes, and per se for isolated qualities. Default to plain English whenever direct clarity is your primary goal.

Questions about "Foreign Phrases in English: Clear Everyday Guide"
Do I need to type accent marks on words like déjà vu and faux pas?
In modern English publications, accent marks are optional for borrowed words that have entered general usage. Major newspapers frequently omit accents to simplify digital typography, writing deja vu without accents. However, maintaining accents in formal correspondence shows precision. Whichever style you choose, remain consistent within the same document.
The style guide allows writers to omit the accents in deja vu.
She preferred to keep the accents in déjà vu for formal publishing.
How is ad hoc different from the standard English word temporary?
Temporary simply indicates that something will not last permanently, such as temporary rain or a temporary employee. Ad hoc adds a critical qualification about purpose: the arrangement exists specifically for one individual situation or problem. An ad hoc team is always temporary, but not every temporary situation is ad hoc.
A temporary worker filled our receptionist vacancy during summer vacation.
The university created an ad hoc committee specifically to review campus safety.
Why do native speakers advise against using per se too often?
Many speakers use per se as casual conversational padding without understanding its philosophical meaning. Per se means intrinsically or by its own nature. If removing per se leaves your sentence meaning unchanged, the phrase is unnecessary clutter. Limit per se to contexts where you must isolate an entity from its surrounding environment.
The contract is not unreasonable per se, but the completion deadline is impossible.
Saying that money per se brings happiness overlooks personal relationships.
Can a policy be both de facto and official at the same time?
No, because the terms describe contrasting sources of authority. Official authority derives from written laws, formal votes, or published company policies. De facto status describes reality established through custom, habit, or practical necessity. When an official policy matches everyday behavior, speakers simply describe it as the official rule.
English is the de facto national language of the United States because no federal statute names an official language.
