El sobregiro causa un problema.

Because sobregiro is a masculine noun in Spanish, so it takes el in the singular.

• el sobregiro = the overdraft
• un sobregiro = an overdraft

There is no simple ending rule here that guarantees gender, so this is something you usually learn with the noun.

El is the definite article, so it means the. It suggests we are talking about a specific overdraft, or about overdraft in a general known sense.

Compare:

• El sobregiro causa un problema. = The overdraft causes a problem.
• Un sobregiro causa un problema. = An overdraft causes a problem.

Both are possible, but they are slightly different in meaning.

Here, causa is a verb, not a noun.

It comes from the verb causar = to cause.

In this sentence:

• el sobregiro = subject
• causa = causes
• un problema = direct object

So causa is third-person singular present tense:

• yo causo = I cause
• tú causas = you cause
• él/ella/usted causa = he/she/you causes

Yes. Causa can also be a noun meaning cause.

For example:

• La causa del problema = The cause of the problem

But in El sobregiro causa un problema, it is clearly a verb because it sits between the subject and the object and means causes.

Because problema is a masculine noun, even though it ends in -a.

This is a common point for English speakers, since many Spanish nouns ending in -a are feminine, but some are masculine, especially words of Greek origin ending in -ma.

Examples:

• el problema
• el sistema
• el programa
• el tema

So:

• un problema
• el problema

not una problema or la problema

Yes, sobregiro is commonly used in Latin America, especially in banking and finance, to mean overdraft.

Depending on the country or context, you may also hear related expressions such as:

• sobregiro bancario = bank overdraft
• girar en sobregiro
• estar en sobregiro

In some regions, other terms may appear, but sobregiro is a solid and widely understandable Latin American term.

A helpful Latin American pronunciation guide is:

• sobregiro → so-bre-HEE-ro
• causa → KOW-sa
• problema → pro-BLE-ma

A few notes:

• The g in giro sounds like a strong h in most of Latin America.
• The stress in sobregiro falls on gi: so-bre-GI-ro
• The stress in problema falls on ble: pro-BLE-ma

Yes. El sobregiro causa un problema follows the very common Spanish pattern:

subject + verb + object

• El sobregiro = subject
• causa = verb
• un problema = object

This is the most straightforward and neutral word order, just like in English: The overdraft causes a problem.

Grammatically, that sentence is possible, but it means something different:

• El sobregiro causa un problema. = The overdraft causes a problem.
• Un problema causa el sobregiro. = A problem causes the overdraft.

So switching the nouns changes who is doing the causing.

Because Spanish often allows more flexible word order than English, articles like el and un help you see what each noun is doing, but in this case the most natural reading is still based on normal word order.

Because causar usually takes a direct object in Spanish.

So you say:

• causar un problema = to cause a problem
• causar daños = to cause damage
• causar estrés = to cause stress

You do not need a preposition like a or de before un problema here.

Yes, but it does not mean exactly the same thing.

• El sobregiro causa un problema. = The overdraft causes a problem.
• El sobregiro es un problema. = The overdraft is a problem.

The first sentence talks about cause and effect.
The second simply says the overdraft itself is problematic.

You could say:

Los sobregiros causan problemas.

Changes:

• el → los
• sobregiro → sobregiros
• causa → causan
• un problema → problemas

This means Overdrafts cause problems or The overdrafts cause problems, depending on context.

You place no before the verb:

El sobregiro no causa un problema.

That means The overdraft does not cause a problem.

This is the normal way to negate a simple Spanish sentence:

• No
  • verb

Example:

• causa = causes
• no causa = does not cause

Yes, two things especially:

1. Gender does not always match word endings

   • problema ends in -a but is masculine

2. A form can look like a noun but actually be a verb

   • causa can mean cause as a noun in other contexts, but here it means causes

So this sentence is simple overall, but it includes two very common Spanish learning points: noun gender and recognizing verb forms from context.
