Introduction
The difference between Desde que and Desde is a common question for English-speaking Spanish learners. Both relate to time and starting points, but they function differently in sentences. This article explains the grammar, shows clear examples, and offers practical usage notes so you can choose the right form with confidence.
Basic meanings: Desde vs Desde que
Desde by itself generally indicates a point in time or location from which something starts. It is often followed by a noun, a date, a time expression, or a prepositional phrase.
Desde que combines the preposition desde with the conjunction que and introduces a full clause. Use it when you want to say since a specific event or action happened, and you need a verb after the starting point.
Simple examples to see the difference
Desde example: Desde 2015 vivo en Madrid.
This means from 2015 I live in Madrid. The starting point is a year (a noun phrase).
Desde que example: Desde que me mudé, estoy más feliz.
This means since I moved, I have been happier. The starting point is the action of moving, which requires a verb.
Grammar rules step by step
When to use Desde (preposition)
Use Desde when the starting point is expressed as a noun, a date, a time, or a location without an explicit clause. Typical structures include:
Desde + noun: Desde enero, Desde las seis
Desde + date/time: Desde 2008, Desde el lunes
Desde + place: Desde la ventana, Desde la estación
Use it with verbs in the main clause but not to introduce a subordinate clause with its own subject and verb. It answers the question from when or from where.
When to use Desde que (conjunction + clause)
Use Desde que when you need to introduce a subordinate clause with a verb. The structure is:
Desde que + subject + verb
This construction highlights a specific event or moment that marks the beginning of a situation. It is equivalent to the English since when followed by a clause.
Examples contrasting both
Desde + noun: Desde el accidente, tiene miedo de conducir.
Desde que + clause: Desde que tuvo el accidente, tiene miedo de conducir.
In the first sentence the starting point is a noun phrase el accidente. In the second sentence the starting point is described by the clause tuvo el accidente, which specifies the action.
Verb tense and aspect with Desde que
Desde que introduces a clause that can take different tenses depending on the timeline you want to express. The main clause tense must agree logically with the subordinate clause.
Present perfect or present after Desde que
When the action introduced by desde que started in the past and continues to the present, Spanish usually uses the present perfect or present in the main clause.
Desde que llegué, no he salido. (Since I arrived, I have not gone out.)
Desde que trabaja aquí, habla mejor español. (Since he started working here, he speaks Spanish better.)
Past situations
To describe a finished situation in the past, use past tenses in both clauses.
Desde que se mudaron, vivieron en paz durante dos años. (Since they moved, they lived in peace for two years.)
Future reference
Although less common, you can use desde que to refer to a point that will begin in the future together with a future tense in the subordinate clause.
No será lo mismo desde que terminen las obras. (It will not be the same once they finish the works.)
Common structures and variations
Desde + hace + duration
Spanish sometimes combines Desde with hace to emphasize duration, typically placing hace before the duration and following it with que or using desde hace without que.
Hace cinco años que estudio español. (I have been studying Spanish for five years.)
Estudio español desde hace cinco años. (I have been studying Spanish since five years ago.)
Desde que vs Desde + hace
Use desde que when you need a clause: Desde que empecé, he mejorado mucho. Use desde hace to indicate duration without a clause: Estudio español desde hace cinco años.
Desde + infinitive (less common)
In some fixed expressions or with an implied subject, you might see Desde followed by an infinitive, but this is less common and often feels more formal or literary.
Desde comer tan temprano, me siento mejor por las mañanas. (This would be unusual in everyday speech; more natural forms exist.)
Pronunciation and stress tips
Both Desde and Desde que are spoken with natural Spanish rhythm. Desde is two syllables DE-sde (pronounced dehs-deh) and Desde que adds the conjunction que after it. In rapid speech, you may hear the final vowel of desde blend with que: desdeque, but writing requires the separate words.
Practical usage: choosing the right form
Quick decision guide
If the starting point is a noun, date, time, or place, use desde. Example: Desde mañana empiezo la dieta.
If the starting point is an action or event you express with a verb, use desde que. Example: Desde que empecé la dieta, me siento mejor.
More real-situation examples
Conversation about work:
Trabajo aquí desde 2019. (I have worked here since 2019.)
Desde que me dieron el ascenso, tengo más responsabilidades. (Since they gave me the promotion, I have more responsibilities.)
Talking about relationships:
Somos amigos desde la universidad. (We have been friends since university.)
Desde que nos conocimos, nos llevamos muy bien. (Since we met, we have gotten along very well.)
Common mistakes and how to avoid them
1. Using Desde que when no verb clause follows. Incorrect: Desde que 2018 vivo aquí. Correct: Desde 2018 vivo aquí.
2. Omitting que when a clause is required. Incorrect: Desde me mudé, estoy más tranquilo. Correct: Desde que me mudé, estoy más tranquilo.
3. Confusing duration expressions. Remember that Desde hace expresses duration with a time period, while Desde que needs a clause or an event: Estudio desde hace dos años vs Desde que terminé la universidad, estudio más.
Cultural and usage notes
Native speakers often choose a shorter option in casual speech, using desde plus a noun when the event can be implied. In formal writing or when clarity is needed, use desde que to specify the action that marks the starting point.
In some regions, speakers may prefer certain temporal constructions over others, but the rules here apply across most varieties of Spanish. When in doubt, think about whether you need a verb after the starting point; that usually solves the choice.
Summary of key points
Use Desde for points in time or locations without a verb. Use Desde que to introduce a clause that describes the event or action marking the start. Make sure verb tenses in both clauses reflect the timeline you mean. For durations, consider desde hace as an alternative.
Conclusion
Mastering the difference between Desde que and Desde is mostly about identifying whether the starting point needs a full clause or a simple noun/time expression. Remember the practical guide: noun/time/place use desde; actions/events requiring verbs use desde que. With these rules and the example sentences above, you can use both forms naturally and accurately in everyday Spanish.
