Common Spanish Mistakes with “Desde entonces”

Introduction

One of the most confusing aspects of Spanish grammar for English speakers involves understanding how to properly use time-related expressions, particularly desde entonces. This phrase, which translates to since then or from that moment on, appears frequently in Spanish conversation and writing, yet many learners struggle with its correct application. Understanding desde entonces requires grasping not only its basic meaning but also the grammatical structures that accompany it, the tenses that follow it, and the subtle differences between similar expressions. In this comprehensive guide, we will explore the most common mistakes learners make with desde entonces and provide clear explanations to help you use this expression with confidence.

What Does Desde Entonces Actually Mean?

Before diving into common mistakes, let us establish a clear understanding of what desde entonces means. The word desde means from or since, while entonces means then. Together, desde entonces refers to a point in time from which something started and has continued until now or until another specified moment.

For example, if someone says Desde entonces, no hemos vuelto a vernos, they are saying Since then, we have not seen each other again. The phrase indicates that a particular moment in the past serves as the starting point for an ongoing or completed action.

Mistake 1: Using the Wrong Verb Tense After Desde Entonces

One of the most frequent errors learners make involves selecting an incorrect verb tense to follow desde entonces. The tense you choose depends on whether the action is still ongoing or has been completed.

When the Action Continues Until Now

If an action began at a specific point in the past and continues to the present moment, use the present perfect tense (pretérito perfecto). This tense is formed with the present tense of haber plus the past participle.

Correct: Desde entonces, hemos vivido en Madrid.
Incorrect: Desde entonces, vivimos en Madrid.

The first sentence correctly uses the present perfect to indicate that they have been living in Madrid since that past moment and continue to live there. The second sentence, using the simple present, sounds awkward and is grammatically incorrect in this context.

When the Action Has Ended

If the action started in the past and has already finished before now, use the simple past tense (pretérito indefinido) if there is a clear endpoint, or the present perfect if the action occurred recently and affects the present.

Example with pretérito indefinido: Desde entonces, trabajé en esa empresa durante diez años.
Translation: Since then, I worked at that company for ten years.

In this case, the action has a clear beginning (the past moment referenced by desde entonces) and a clear ending (ten years later when the employment ended).

Mistake 2: Confusing Desde Entonces with Other Time Expressions

English speakers often confuse desde entonces with similar Spanish expressions, leading to incorrect usage. Understanding the differences between related phrases is essential.

Desde Entonces vs. Desde Que

Desde que (since) introduces a clause with a specific event or condition. Desde entonces refers to a point in time without introducing a new clause.

Correct with desde que: Desde que llegué a España, he aprendido mucho español.
Translation: Since I arrived in Spain, I have learned a lot of Spanish.

Correct with desde entonces: Llegué a España hace un año. Desde entonces, he aprendido mucho español.
Translation: I arrived in Spain a year ago. Since then, I have learned a lot of Spanish.

Notice that desde que combines the introductory clause and the result in one sentence, while desde entonces typically appears after already mentioning the past event.

Desde Entonces vs. Desde Hace

Desde hace means for when referring to duration and is used with the present tense in Spanish (unlike English). Desde entonces refers to a specific point in time rather than a duration.

Correct with desde hace: Estudio español desde hace tres años.
Translation: I have been studying Spanish for three years.

Correct with desde entonces: Comencé mis estudios en 2021. Desde entonces, he estudiado español todos los días.
Translation: I began my studies in 2021. Since then, I have studied Spanish every day.

Mistake 3: Incorrect Word Order and Placement

Another common error involves placing desde entonces in awkward positions within a sentence. In Spanish, this phrase can appear at the beginning, middle, or end of a sentence, but placement affects clarity and naturalness.

Natural Placement Options

At the beginning: Desde entonces, no hemos tenido noticias de él.
Translation: Since then, we have not heard from him.

In the middle: No hemos tenido, desde entonces, noticias de él.
Translation: We have not heard, since then, from him.

At the end: No hemos tenido noticias de él desde entonces.
Translation: We have not heard from him since then.

All three placements are grammatically correct, though placing it at the beginning or end sounds more natural to native speakers. Avoid placing desde entonces between the auxiliary verb and the past participle in compound tenses.

Mistake 4: Mixing Perspectives with Desde Entonces

Learners sometimes make errors when desde entonces is used in narratives that switch between describing past events and their ongoing effects. Maintaining consistent perspective is crucial.

Incorrect: Vi a María en la estación. Desde entonces, la veo cada semana. (mixing past simple with present)

Better: Vi a María en la estación hace un año. Desde entonces, la veo cada semana.
Translation: I saw María at the station a year ago. Since then, I see her every week.

Or: Había visto a María en la estación. Desde entonces, la veía cada semana.
Translation: I had seen María at the station. Since then, I saw her every week.

The key is ensuring that the timeline makes sense. When you use desde entonces, the reader should understand what entonces refers to, which requires clear context.

Mistake 5: Overusing or Underusing Desde Entonces

Some learners avoid desde entonces altogether because they are uncertain about its usage, while others overuse it even when simpler constructions would be more appropriate.

Knowing When to Use It

Desde entonces is most effective when you want to emphasize that a significant time has passed since a particular moment. If you are simply stating a fact about duration, other expressions may be more suitable.

Appropriate use: El accidente ocurrió en 2015. Desde entonces, la ciudad ha cambiado completamente.
Translation: The accident occurred in 2015. Since then, the city has changed completely.

Less appropriate: Nací en 1995. Desde entonces, he vivido en varios países. (Better: He vivido en varios países durante mi vida.)

Mistake 6: Forgetting About Negative Constructions

In negative sentences, learners sometimes forget that desde entonces still requires proper tense agreement, even when negation is involved.

Correct: No lo he visto desde entonces.
Translation: I have not seen him since then.

Incorrect: No lo veo desde entonces. (This changes the meaning to a habitual non-seeing rather than a completed action.)

The present perfect with negation emphasizes the duration of non-occurrence from that past moment until now, which is the typical intended meaning.

Practical Tips for Mastering Desde Entonces

To solidify your understanding of desde entonces, consider the following practical strategies:

First, always identify the reference point. What moment does entonces refer to? Make sure this is clear from context or explicitly stated earlier.

Second, determine whether the action is ongoing or completed. This decision directly determines which tense to use.

Third, practice converting between desde entonces and desde que constructions. This comparison helps clarify the differences between these expressions.

Fourth, read authentic Spanish materials and notice how native speakers use desde entonces. Pay attention to the verb tenses that follow and the contexts in which the phrase appears.

Finally, create your own sentences using desde entonces with different time frames and tenses. Speaking and writing are the best ways to internalize these patterns.
