Hablar is a common Spanish verb that means "to speak" or "to talk". It's a very simple -AR verb and likely one of the very first verbs you would learn in any beginner level Spanish class. Here is how to conjugate the verb hablar:

Yo hablo - I speak
Tú hablas - You speak (informal)
Él habla - He speaks
Ella habla - She speaks
Usted habla - You speak (formal)
Nosotros hablamos - We speak
Vosotros habláis - You guys speak/ You all speak (informal)
Ellos hablan - They speak (group of males or group of mixed gender)
Ellas hablan - They speak (group of females)
Ustedes hablan - You all speak / You speak (formal)

A few examples using hablar, translated from Spanish into English:

Ellas hablan con los chicos. - They speak with the boys.
Yo hablo por teléfono con mi madre. - I talk on the telephone with my mother.
Ustedes hablan todos los días. - You talk every day.

Spanish verb conjugation is perhaps the most crucial concept for beginner students. So much of what new students learn centers on understanding how to conjugate Spanish verbs. This is because verbs and subjects are the foundational elements of sentence structure and therefore are the foundation of virtually everything you say in Spanish. It’s no different for English—by the way—we just don’t often realize it. 

Subject Pronouns or Subjects
In Spanish, conjugating verbs is simple, but it does require some explanation as well as a good deal of verbal practice before you’ll understand it completely. Conjugating verbs always begins with the subject of the sentence because we need to know who is acting out the verb. You may hear your Spanish professor refer to subjects as 'subject pronouns', but I think that term confuses people. In my simple mind, they are subjects and it doesn't need to be any more complicated than that. So the subject is the noun (person, place, or thing) that is doing the verb (action word). Common subject are I, you, he, she, it, we, they, etc.

Spanish Verbs
Verbs are the action word of a sentence, such as run, eat, play, speak, etc. Usually verbs are simple to imagine in your mind. For example, it’s easy to imagine someone running, eating, playing, and speaking. These would all be examples of verbs in their infinitive (pure) form: to run, to eat, to play, to speak.

Spanish Verb Conjugation
Conjugating verbs requires that you match a subject with a verb. And the most important thing to remember is that the subject determines how the verb is conjugated.

When you conjugate a verb, you remove the to and replace it with a subject. In other words, you actually change the verb from its infinitive form (to eat) to a conjugated form when matching it up with a subject. You also sometime change the ending of the verb slightly, such that He + to eat becomes He eats. Or She + to run becomes She runs.

This is the essence of verb conjugation, which is the foundation of the Spanish language. It may seem simple in English, but conjugating in Spanish actually presents a couple more challenges because 1) it’s not your native language and 2) the conjugations are much more complex than simply adding an “s” to the end of each verb. This is a quick blog post meant to help you understand the basics of conjugating verbs in Spanish.

Subject:   Ella = she
Verb:        Comer = to eat

Ella + Comer = Ella come = She eats

I speak with a lot of people who want to speak Spanish, most of whom ask questions about the language and wanting my recommendations for an effective Spanish course. It’s common for these people to be curious about how difficult it is to learn Spanish. They aren’t asking how difficult it is to learn the language in full. What they really want to know is ‘how long will it take me to learn enough Spanish to feel comfortable getting around in a foreign country or in a light conversation with a native Spanish speaker?’

How long it takes you to learn conversational Spanish depends on you. Are you someone who can recognize patterns, enjoys music, and understands basic math? If you said yes, then your chances of learning Spanish quickly are very good.

Having an appreciation for patterns, music, and math are important because they help you understand the building blocks of the Spanish language—Verbs. Spanish Verbs, along with subjects, are some of the most basic elements of the Spanish language and having a clear understanding of them will help you speak Spanish more than any other concept. And once you understand the relationship between subjects and verbs, you ability to speak and grasp the more advanced concepts greatly improves.

When setting out on their journey to learn Spanish, many students ask ‘where do I begin?’ Formal Spanish language courses taught by your community college or in a textbook will start by teaching you how to say things like ‘the’, ‘a’, and ‘and’. Then you’ll advance to—dare I say—nouns! By the end of week one you’ll be saying things like, ‘the dog’, ‘the food’, and ‘the house’. My Beginner Spanish course takes a different approach, however. The first four lessons of Beginner Spanish aim to solidify the student’s ability to match a subject with a verb and then create a basic sentence. After just an hour you’ll be saying things like ‘I eat the cookie’ and ‘we watch the movie.’ Shortly thereafter you’ll be able to ask and answer questions in complete sentences.

This type of verb-based learning has two benefits. First, it puts a lot of Spanish words into your vocabulary very quickly so as to prepare you for actual conversations you might have. Second, it establishes a foundation in your brain that helps you understand all the subsequent Spanish language concepts that you will learn.
