El servicio exprés reduce el plazo de entrega.

Because servicio is a masculine noun in Spanish, so it takes the masculine article el.

• el servicio = the service
• un servicio = a service

Like many nouns ending in -o, servicio is masculine, although there are exceptions in Spanish, so it is still something you learn noun by noun.

Exprés means express, rapid, or expedited. In this sentence, servicio exprés means an express service or expedited service.

It works like an adjective here, describing the type of service.

In Latin America, exprés is widely understood, especially in shipping, delivery, transportation, and business contexts.

The accent mark in exprés shows where the stress goes: ex-PRÉS.

This word is adapted from foreign usage and is commonly written with the accent in Spanish to reflect normal Spanish pronunciation. Without the accent, learners might not know which syllable to stress.

So:

• exprés → stress on the last syllable

Because reduce is the conjugated verb, while reducir is the infinitive.

Here, the subject is El servicio exprés, which is third person singular, so the verb must match it:

• reducir = to reduce
• reduce = it reduces / reduces

So the structure is:

• El servicio exprés = subject
• reduce = verb
• el plazo de entrega = object

In Spanish, verb endings show the subject.

For reducir in the present tense:

• yo reduzco = I reduce
• tú reduces = you reduce
• él / ella / usted reduce = he / she / it / you reduce

Since the subject is El servicio exprés, which is like it, the correct form is reduce.

Plazo usually means a time period, deadline, or allowed time frame.
Entrega means delivery or handing over.

So el plazo de entrega means something like:

• the delivery time
• the delivery period
• the delivery time frame
• sometimes the delivery deadline, depending on context

It is a common business and logistics expression in Spanish.

Because Spanish usually connects nouns with de where English often uses one noun as an adjective-like modifier.

Compare:

• delivery time → plazo de entrega
• car door → puerta del coche
• payment method → método de pago

So de often means something like of or for, even though in natural English we may not translate it literally.

Yes, often you can, but the nuance is a little different.

• tiempo de entrega = delivery time, more general
• plazo de entrega = delivery period, lead time, or expected/allowed delivery window

In business, shipping, and contracts, plazo can sound a bit more formal or specific than tiempo.

So El servicio exprés reduce el tiempo de entrega is also a natural sentence, but plazo de entrega may fit better in professional or logistical contexts.

Because in Spanish, most adjectives normally come after the noun.

So:

• servicio exprés
• coche rojo
• entrega rápida

This is one of the big differences from English, where adjectives usually come before the noun.

That said, adjective placement in Spanish can sometimes change meaning or emphasis, but with exprés, the normal order is servicio exprés.

Yes, but the original order is the most neutral and natural:

• El servicio exprés reduce el plazo de entrega.

You could also say:

• El plazo de entrega lo reduce el servicio exprés.

That version adds emphasis, but it is less neutral and would usually be used only in a context where you want to highlight the delivery time specifically.

For a learner, the basic subject + verb + object order is the best pattern to use here.

A simple approximation is:

• eks-PRES

More specifically:

• ex sounds like eks
• prés has the stress

So the full phrase:

• servicio exprés ≈ ser-BEE-syo eks-PRES

In many Latin American accents:

• c before i sounds like s, so servicio sounds like serbisyo or serbisyo depending on how narrowly you listen.

Usually yes. Reducir often works very similarly to English to reduce.

Examples:

• reduce costos = reduces costs
• reduce el tiempo = reduces the time
• reduce el plazo de entrega = reduces the delivery time frame

In everyday Spanish, you might also hear:

• disminuir = to decrease
• acortar = to shorten

So similar alternatives would be:

• El servicio exprés disminuye el plazo de entrega.
• El servicio exprés acorta el plazo de entrega.

All are possible, but reduce is perfectly natural here.
