törmäyttämällä

törmäyttämällä is a Finnish adverbial form used to express the means or manner "by colliding" or "by causing a collision." It is formed as a gerund-like construction that indicates an action performed as the method or instrument for producing an outcome.

The term appears in contexts where collision is the intentional or instrumental cause of an effect. Common uses include descriptions in physics and engineering (e.g., particle accelerators, impact testing), traffic and accident reports, and figurative language where opposing forces or ideas are made to interact forcefully.

Examples:

- Fysiikassa hiukkaset voidaan hajottaa törmäyttämällä ne toisiinsa. (In physics, particles can be broken apart by colliding them with one another.)

- Räjähdys syntyi törmäyttämällä kaksi paineastiaa tahattomasti yhteen. (The explosion resulted from accidentally colliding two pressure vessels.)

Related forms include the base verb törmätä ("to collide") and nominal forms such as törmääminen ("collision"). Depending on context, törmäyttämällä can imply deliberate action (causing a collision) or describe a process that occurs through collisions. Stylistically it is neutral and typically appears in descriptive or technical language rather than colloquial speech. Translations into English most often render it as "by colliding," "through collision," or "by causing a collision," depending on nuance.
