Exact vs. précis

The French words 'exact' and 'précis' both relate to the concepts of accuracy and detail. However, they are used in slightly different contexts and have nuanced meanings that can change the intended message. Understanding the differences between these two terms helps in their appropriate application in the French language.

Exact

'Exact' generally refers to something that is correct or accurate without errors. It is often used to confirm information, dates, or facts that match perfectly with what is known or expected.

(The exact time is 8 AM.)
Votre réponse est exacte.
(Your answer is correct.)
Il est arrivé à lheure exacte convenue.
(He arrived at the exact agreed time.)

Précis

While 'précis' still deals with accuracy, it leans more towards the idea of being precise, detailed, and specific, often implying a level of meticulousness or fine detail.

(I want a more precise explanation of the situation.)

(This job requires a very precise measurement of ingredients.)

(She always describes the events in a very precise manner.)

Summary

In summary, 'exact' and 'précis' though closely related, are not interchangeable; 'exact' is used when referring to correctness or accuracy in conformity with an established fact or standard, while 'précis' emphasizes specificity, detail, and meticulousness in presentation or measurement. Recognizing these distinctions ensures that one communicates with greater accuracy in French-speaking contexts.
