A1 Expression カジュアル

Es mentira

It's a lie

意味

Stating that something is false or untrue.

🌍

文化的背景

In Spain, calling out a lie can be very direct. It is common in debates to hear 'Eso es mentira' without it necessarily being a personal insult, but rather a factual challenge. Mexicans often use 'Es puro cuento' or '¡Neta!' to challenge truth. Direct accusations of lying are often avoided in formal settings to maintain 'face'. The word 'verso' is a very common local synonym for 'mentira'. If someone is 'chamuyando' (sweet-talking/lying), people say 'es todo un verso'. In casual Colombian speech, 'paja' is used frequently. 'Hablar paja' means to talk nonsense or lie.

⚠️

Careful with the tone

Saying 'Es mentira' with a sharp tone can start a fight. Use a softer voice if you just mean 'I don't think that's right'.

🎯

The 'Mentira' Interjection

You can just shout '¡Mentira!' as a one-word reaction. It's very common and very effective.

Face-saving

In Latin America, if you aren't sure, use 'No estoy de acuerdo' (I don't agree) instead of calling it a lie.

自分をテスト

Choose the most natural way to say 'It's a lie' in Spanish.

Tu amigo dice que mañana es Navidad, pero es julio. Tú dices:

✓ 正解! ✗ おしい! 正解: Es mentira

In Spanish, we drop the 'un' and use the verb 'ser'.

Complete the sentence with the correct form of the verb 'ser'.

Lo que me dijiste ayer ___ mentira.

✓ 正解! ✗ おしい! 正解: era

Since the speaker is referring to something said 'ayer' (yesterday), the imperfect 'era' or preterite 'fue' is needed. 'Era' is more common for ongoing states in the past.

Match the phrase to the situation.

1. '¡Mentira!' (Shocked) | 2. 'No es verdad' (Polite) | 3. 'Es puro cuento' (Slang)

✓ 正解! ✗ おしい! 正解: 1-B, 2-A, 3-C

'Mentira' expresses shock, 'No es verdad' is polite for bosses, and 'puro cuento' is Mexican slang.

Complete the dialogue.

A: ¿Sabías que el profesor no viene hoy? B: ________, lo acabo de ver en el pasillo.

✓ 正解! ✗ おしい! 正解: Es mentira

The second part of the sentence ('I just saw him in the hallway') contradicts the first part, so 'Es mentira' is the logical choice.

Match the Spanish phrase with its English equivalent.

1. Mentira piadosa | 2. Mentira cochina | 3. Todo es mentira

✓ 正解! ✗ おしい! 正解: 1-B, 2-C, 3-A

These are common collocations with the word 'mentira'.
