Basic meanings: marcar vs subrayar
The verb marcar generally means to mark, check, or indicate something. It has broad uses beyond writing: pressing a button, marking an attendance list, or signaling an option.
The verb subrayar specifically means to underline or emphasize by drawing a line under text. It is mainly used for written or printed material and focuses on visually highlighting text.
Simple dictionary-style explanations
marcar: to mark, to check, to dial, to score, to indicate. Use when you want to signal or identify something in many contexts.
subrayar: to underline, to emphasize by drawing a line under words. Use when you physically or digitally underline text to show importance.
Everyday contexts and examples
Here are typical situations a beginner might encounter, with practical Spanish examples and short translations to show which verb fits.

subrayar el libro para recordar las ideas principales.
To underline the book to remember the main ideas.

Editing a document

On the exam, I marked the correct answer with an X.

When to prefer subrayar
Use subrayar when you physically or digitally draw a line under words or when you emphasize a phrase by highlighting it in text. It is more specific than marcar and usually applies to written text.
Common examples and short situations
Antes del examen, subrayé todas las definiciones importantes para repasarlas.

Everyday vocabulary with subrayar
subrayar una palabra — to underline a word
subrayar una idea — to emphasize an idea (by underlining)
subrayado — underlined (adjective)
Overlap and subtle differences
Sometimes both verbs can be correct, but the nuance changes. If your focus is on indicating importance without specifying how, marcar works. If you mean specifically drawing a line under text, use subrayar.
Example where both are possible
En la lista, puedes marcar o subrayar los elementos importantes.
On the list, you can mark or underline the important items.
Nuance: marcar suggests checking off or signaling, while subrayar suggests using a pen or highlighter to draw attention visually.
Practical tips for beginners
Tip 1: Link subrayar to the image of a line beneath words. If you picture underlining, subrayar is the safe choice.
Tip 2: Use marcar for lists, boxes, buttons, or when you mean selecting rather than underlining.
Tip 3: Learn common collocations. For example, marcar la casilla and marcar el número are frequent in everyday tasks. Subrayar la frase and subrayar las ideas are common when studying.
Classroom practice exercise
Exercise instructions in Spanish for simple classroom use
Lee el párrafo y subraya las cinco palabras más importantes.
Read the paragraph and underline the five most important words.
En la lista de compras, marca los artículos que ya compraste.
On the shopping list, check the items you already bought.
Common mistakes and how to avoid them
Mistake 1: Using subrayar for dialing a phone. Avoid saying subraya el número when you mean dial; instead say marca el número.
Mistake 2: Using marcar when you want to convey physical underlining. Avoid marca la frase if you mean draw a line under it; instead use subraya la frase.
Mistake 3: Confusing contexts with digital text. When underlining on a computer, both verbs appear, but beginners should keep the physical action in mind: if you are highlighting text, subrayar is clearer.
