A1 Expression ニュートラル

No lo sé.

I don't know.

意味

Used to express lack of knowledge.

🌍

文化的背景

Spaniards are often very direct. While 'No lo sé' is common, you will very frequently hear 'Ni idea' (Not an idea) among friends, which isn't considered rude. In Mexico, people might use 'Quién sabe' (Who knows) as a more idiomatic and slightly softer alternative to 'No lo sé'. Argentines might use 'Qué sé yo' (What do I know) to express that they don't know and perhaps don't care, or as a filler phrase.

💡

The 'Lo' is your friend

Including 'lo' makes you sound more like a native speaker than just saying 'No sé'.

⚠️

Accent matters

Always write 'sé' with an accent. 'Se' (without accent) is a pronoun used in 'Se vende' or 'Se lava'.
