スペイン語話者がよく犯す間違い

A very common mistake for Spanish speakers is to confuse -ed そして -ing adjectives, especially when talking about themselves.

• 誤り： I am boring. (This means YOU cause boredom in other people.)
• 正しい： I am bored. (This means YOU feel boredom.)

Another common error is using the wrong adjective to describe a thing:

Always remember: people feel -ed, and things/situations are -ing (because they cause the feeling).
