9. "To let a frog out of your mouth"
Language: Finnish
Translation: Päästää sammakko suusta
Meaning: To say the wrong thing
Finnish idioms have a lovely tone to them, often referencing Mother Nature and their homeland. Having “rye in your wrists” means to be physically strong, for instance, while “own land strawberry, other land blueberry” reflects Finns’ love for the motherland. “Letting a frog out of your mouth” means to say the wrong thing, which makes sense, as spitting a frog at someone is almost always the wrong thing to do.
