💡 Grammar Points

The 'It' Form

In this meaning, 'costó' almost always refers to a thing (like 'it') or a singular event, so the 'él/ella/usted' form is the most common usage.

❌ Common Pitfalls

Confusing Past Tenses

Mistake: "Using the imperfect 'costaba' when asking for a specific price: '¿Cuánto costaba?'"

Correction: Use the preterite 'costó' for a finished action (a specific purchase): '¿Cuánto costó?' The imperfect 'costaba' describes what things used to cost generally.

⭐ Usage Tips

Focus on the Object

The subject doing the action (the thing that cost) is almost always placed after the verb: 'Costó cien dólares la entrada' (The ticket cost a hundred dollars).

A determined cartoon character strains and sweats while pushing a massive, round, gray boulder up a steep, grassy incline.

The character's struggle to push the boulder up the hill visualizes the meaning "it was difficult" (required effort).

💡 Grammar Points

Using Effort Verbs

When 'costar' means 'to take effort,' it works like the verb 'gustar.' You need an indirect object pronoun (me, te, le, nos, etc.) to show who experienced the difficulty. Example: 'Le costó' (It was difficult for him/her).

Follow-up Action

The action that was difficult usually follows 'costó' as an infinitive verb (e.g., 'costó terminar' - it was hard to finish) or a noun (e.g., 'costó el ascenso' - the promotion was hard).

❌ Common Pitfalls

Direct Translation

Mistake: "Saying 'Yo costé' to mean 'I struggled.'"

Correction: You must use the third-person form 'costó' (or 'costaron') and an indirect pronoun: 'Me costó' (It was difficult for me/I struggled).

⭐ Usage Tips

Emphasizing Difficulty

To emphasize just how hard it was, frequently add 'mucho' (a lot) or 'un montón' (a ton) after 'costó': 'Costó muchísimo'.

Frequently Asked Questions

What is the difference between 'costó' and 'costaba'?

'Costó' (preterite) is used for a specific, completed purchase in the past ('The car cost $10,000'). 'Costaba' (imperfect) describes what things generally used to cost, or the cost over a period of time in the past ('Back then, gas cost less').

Why does 'costó' have an accent mark?

The accent mark on the 'o' is essential! It tells you that the stress falls on the final syllable, marking it as the simple past tense (preterite) of the verb. If it didn't have the accent (costo), it would be the noun meaning 'cost' or the 'yo' present tense form of 'costar' in some regions, which is incorrect standard usage.
