“Minucioso” fits most cases; “exhaustivo” and “a fondo” work when you mean fully detailed.
“Thorough” looks simple in English, yet it can point to a few different ideas: careful, detailed, complete, or done all the way through. Spanish has strong options for each meaning. Pick the one that matches what you’re trying to say, and your sentence will sound natural.
This page gives you the clean translations, plus the small shifts in meaning that matter in essays, emails, and everyday speech. You’ll see when to use an adjective, when a phrase sounds better, and how to build sentences that feel like Spanish, not a word swap.
What “Thorough” Means In Your Sentence
Before you choose a Spanish word, lock in the English meaning you want. “Thorough” can mean “careful with details,” “covers everything,” or “done fully.” Spanish often uses different words for those angles.
Thorough As Careful And Detail-Focused
If you mean someone works with care, checks details, and doesn’t miss small points, Spanish leans toward minucioso or meticuloso. These describe the person, the work, or the method.
Thorough As Covers Everything
If you mean a review, study, or report includes all parts, Spanish often uses exhaustivo. It signals full coverage and depth, like a full review of every section.
Thorough As Done Fully
If you mean an action is done “all the way,” Spanish often prefers a phrase, not a single adjective. Common picks are a fondo (“in depth”) and por completo (“completely”).
Best Translations For “Thorough” In Spanish
Minucioso
Minucioso is a top choice for “thorough” when you mean careful attention to detail. It fits schoolwork, job tasks, research notes, and personal habits.
Sample uses: una revisión minuciosa (a thorough review), un análisis minucioso (a thorough analysis). It can describe a person too: Es minuciosa (“She’s thorough”).
Meticuloso
Meticuloso is close to “meticulous.” It highlights method, order, and care in steps. Use it when the process matters, like lab work, writing, or editing.
Common pairings: un trabajo meticuloso, un enfoque meticuloso. It sounds a bit formal, which can be a plus in academic writing.
Exhaustivo
Exhaustivo matches “thorough” when you mean wide coverage and depth. It’s a strong fit for reports, reviews, audits, and research.
Common pairings: un informe exhaustivo, un estudio exhaustivo, una búsqueda exhaustiva. In an essay, it signals you covered all angles.
Detallado
Detallado means “detailed.” It works when “thorough” points to detail in writing, explanation, or documentation. It’s often the smoothest option in everyday contexts.
Sample uses: una explicación detallada, instrucciones detalladas. If you want a softer tone than exhaustivo, this is a solid pick.
Completo
Completo means “complete.” Use it when “thorough” means nothing is missing. It fits checklists, forms, plans, and summaries.
Sample uses: un resumen completo, una lista completa. If you mean “covers everything,” completo can work, though exhaustivo can sound more academic.
A Fondo
A fondo is a go-to phrase for “thoroughly” or “in depth.” It often sounds more native than forcing an adjective into the sentence.
Sample uses: Investigué el tema a fondo (“I researched the topic thoroughly”), Revisemos esto a fondo (“Let’s review this thoroughly”).
Por Completo
Por completo means “completely.” Use it when “thorough” means “fully done,” like cleaning, finishing, or removing something.
Sample uses: Limpié la cocina por completo (“I cleaned the kitchen thoroughly”), Leí el documento por completo (“I read the document all the way through”).
Choosing The Right Option In Common Situations
Now let’s match the translation to what you’re doing: writing an essay, emailing a teacher, talking about research, or describing a person. The goal is to pick the Spanish that fits the task.
School Essays And Academic Writing
For formal writing, exhaustivo, meticuloso, and minucioso carry the tone most teachers expect. Detallado can work too, especially for explanations and steps.
If your sentence is about coverage of sources or sections, lean toward exhaustivo. If your sentence is about careful method, lean toward meticuloso or minucioso.
Emails And Professional Notes
In workplace Spanish, you’ll often see detallado and minucioso in a calm, professional tone. For audits, reports, or reviews, exhaustivo is common.
Try patterns like: Gracias por la revisión minuciosa or Adjunto un informe detallado. Both sound clean and direct.
Talking About A Person
To describe a person as “thorough,” minucioso is the easiest fit. Meticuloso adds a sense of method and order, often tied to work style.
Samples: Es minucioso con los detalles (“He’s thorough with details”), Es meticulosa al revisar (“She’s thorough when checking”).
Talking About Actions
When English uses “thoroughly” to describe how an action was done, Spanish often prefers an adverb phrase. A fondo works for research, review, discussion, and reading. Por completo fits finishing tasks and doing something fully.
Samples: Lo revisé a fondo (“I checked it thoroughly”), Lo limpié por completo (“I cleaned it thoroughly”).

Some English sentences use “thorough” as a broad praise word, without a clear target. In Spanish, that can feel vague. In those cases, pick what you praise: detail, coverage, or completion.
If You Praise Detail
Use minucioso or detallado. These tell the reader what was good: attention to details or lots of detail in the output.
If You Praise Coverage
Use exhaustivo. It signals you didn’t skip sections, and you worked through all angles of the topic.
If You Praise Completion
Use por completo or completo. These tell the reader nothing is missing or the task was finished fully.
