Ideasi

Ideasi is a Finnish phrase meaning "your idea." It is formed by the noun idea with the second-person singular possessive suffix -si, producing ideasi. The phrase refers to an idea belonging to the person being addressed and is common in everyday speech.

Usage of ideasi is frequent in conversations, education, and brainstorming. Examples include Mikä on ideasi? “What is your idea?” and Jaa ideasi. “Share your idea.” The construction is primarily used with a singular idea owned by the listener, though broader contexts can be expressed through other phrasing when talking about multiple ideas or when addressing more than one person.

Grammar and form: Ideasi functions as a noun phrase and carries the second-person possessive meaning through -si. It marks the possessor as the listener. In contexts involving several people or several ideas, speakers typically rephrase to alternatives such as mitä ideoita teillä on? “What ideas do you have?” or teidän ideanne, to indicate plural ownership or different syntactic arrangements.

Etymology: The base word idea is a widely used loanword in Finnish, adopted into the language in the modern era. The suffix -si is a standard second-person possessive ending in Finnish grammar, used to signal possession by the person being addressed.
