Klaviatuuril

Klaviatuuril is the Estonian adessive form of the noun klaviatuur, meaning keyboard. In Estonian grammar, the adessive case expresses location or position, roughly translating to "on" or "at" in English. Therefore klaviatuuril means "on the keyboard" and is used to describe where an action takes place or where something is located, such as hands, keys, or instructions related to keyboard use.

Formation and usage: The base form klaviatuur receives the adessive suffix -il, yielding klaviatuuril. The construction is standard for indicating a surface location. It appears in instructional texts, user guides, and descriptive sentences about typing, computer work, or ergonomics.

Examples: Asetage käed klaviatuuril õigesse asendisse. Vajutage klahvi X klaviatuuril. Käed on klaviatuuril kirjutamise ajal. In English, these phrases correspond to "Place your hands on the keyboard in the correct position," "Press the X key on the keyboard," and "Hands are on the keyboard while typing."
