Question 1

What is the role of -se after aplica?

Accepted Answer

The -se is a clitic pronoun that creates a passive or middle-voice construction called “passive se.” Here, aplica-se means is applied rather than an active “applies.” It shifts the focus onto o desconto (the discount) as the recipient of the action.

Question 2

Why does se attach at the end of aplica instead of coming before it?

Accepted Answer

Portuguese pronoun placement follows specific rules:  
- At the beginning of a main clause, enclisis is mandatory, so you attach the pronoun after the verb (aplica-se).  
- In subordinate clauses or after certain words (e.g. negatives like não), you use proclisis (não se aplica).  
- Mesoclisis (inserting the pronoun into the middle) is rare and mostly literary.

Question 3

Could we rephrase this sentence using the passive voice with ser, like é aplicado?

Accepted Answer

Yes. You can say:  
 O desconto é aplicado automaticamente ao preço final.  
This uses the auxiliary ser + past participle aplicado. Both forms are correct; aplica-se (passive se) is simply more concise and common in notices or labels.

Question 4

Why is ao used before preço final?

Accepted Answer

Ao is the contraction of the preposition a (to/at) + the definite article o (the, masculine singular). Thus, ao preço final literally means to the final price. Contractions like ao (a + o) and do (de + o) are very common in Portuguese.

Question 5

What’s the difference between preço final and preço total?

Accepted Answer

They often overlap, but:  
• Preço final stresses the amount after all adjustments (discounts, taxes).  
• Preço total highlights the overall sum you pay.  
In many contexts they’re interchangeable, though preço final is slightly more precise when referring to the end result after applying a discount.

Question 6

Why is the adverb automaticamente formed with -mente?

Accepted Answer

Portuguese creates adverbs of manner by adding -mente to the feminine singular of an adjective. For example:  
 automático (masculine adjective) → automática (feminine) → automaticamente (adverb).  
This is equivalent to adding -ly in English (automatic → automatically).

Question 7

Where can the adverb automaticamente appear in the sentence?

Accepted Answer

Adverbs of manner are flexible:  
• Before the verb: Automaticamente, aplica-se o desconto ao preço final.  
• After the verb: Aplica-se automaticamente o desconto ao preço final.  
• After the object: Aplica-se o desconto ao preço final automaticamente.  
All positions are grammatically correct; placing it right after the verb is most common for clarity.

Question 8

How do you pronounce preço, and why is there a ç?

Accepted Answer

The letter ç (c cedilha) always represents the /s/ sound before a, o, or u. In European Portuguese, preço is pronounced approximately /ˈprɛ.su/:  
• prê as in “pet” but closed-mid.  
• -ço like “su” (not /ks/).  
The cedilla simply tells you it’s an s sound rather than a hard k sound.
