Controllabilitysanan

Controllabilitysanan is a term used in Finnish-language linguistic discussions to refer to the English noun controllability in a metalinguistic context. It is not a standard Finnish dictionary entry, but it can appear when describing or translating vocabulary items in academic or educational texts.

Composition and meaning: The base is controllability, formed in English from control and -ability. The word sana means "word" in Finnish, and sanan is its genitive form "of the word." When combined, controllabilitysanan literally means "the controllability word" and is used to signal that the text is discussing the specific word rather than its sense.

Usage: The compound is mainly used to talk about vocabulary items, to label glosses, or in examples illustrating Finnish word formation. It is not a common everyday expression and appears primarily in linguistic analyses, dictionaries, or translation notes that reference individual terms.

Controllability as a technical term: Separately from its meta-linguistic use, controllability is a key concept in control theory describing whether a system's state can be driven to any desired state with suitable inputs. In linear systems, this is determined by the controllability matrix; in nonlinear settings, other criteria apply.
