Hilda
Chaos comes to Trolberg when the bell system begins to ring every hour, inspiring Hilda and friends to hatch an elaborate scheme to quiet the noise.

Very common attention-getter in everyday speech. Used to call someone's attention informally, much like 'hey' in English. Not rude, but clearly informal.
Extremely common expression of encouragement or urgency. Can push someone to hurry, cheer them on, or signal it is time to leave. Tone depends heavily on context and delivery.
The standard expression for apologising in Latin American Spanish. Softer than 'perdón', which is more abrupt. 'Lo siento mucho' adds emphasis. Used for genuine regret rather than just bumping into someone.
An emphatic expression of agreement or affirmation. Signals strong confirmation of what the other person just said. More expressive than a plain 'sí'.
Borrowed from radio and military communication to mean 'message received and understood'. Used informally among friends, especially when role-playing or coordinating a plan.
A versatile exclamation expressing surprise, admiration, sarcasm, or mild displeasure depending on tone. In Latin American Spanish it often expresses surprise or mild irony.
