osvtlením

Osvtlením is not a standard Czech word. It is typically a misspelling or ASCII rendering of the instrumental form osvětlením, which means by illumination or through illumination. In formal writing the diacritized form osvětlením is used; non-diacritic variants such as osvetlením are common in plain-text texts, but osvtlením is generally considered incorrect.

Etymology and meaning: The form derives from the root osvětl- from the verb osvětlit (to illuminate) and the noun osvětlení (illumination, lighting). The instrumental singular osvětlením expresses the means or manner by which illumination is achieved, i.e., by illumination.

Usage: The term appears in technical and everyday Czech when discussing lighting or illumination. In standard Czech, the correct forms are osvětlit for the verb, osvětlení for the noun, and osvětlením for the instrumental. Osvtlením should be avoided in formal texts and corrected to osvětlením. The word is closely related to osvětlovač (illuminator) and to osvětlování (the act of lighting).

See also: osvětlení, osvětlování, osvětlení. These related terms cover the nouns and activities connected with lighting and illumination, while osvtlením serves as an nonstandard orthographic variant of osvětlením.
