katsojaa

Katsojaa is the partitive singular form of the Finnish noun katsoja, meaning a viewer, spectator or observer. The base word katsoja is derived from the verb katsoa ("to look, to watch") with the agentive suffix -ja, and denotes a person who watches events, performances, broadcasts or other visual media.

In Finnish grammar the form katsojaa is used in partitive contexts such as expressing an indefinite quantity, ongoing actions, certain objects of verbs, and in many common reporting phrases (for example in audience counts and attendance reports). It appears in everyday language about theatre and concert audiences, sports spectators, television and streaming audiences, and online viewership.

Related lexical items include katsojat (nominative plural), katsojia (partitive plural), katsojan (genitive singular) and compound terms like katsojamäärä (audience size) and katsojaluku (viewer count). In media and cultural reporting katsojaluvut and katsojamäärät are often used to describe popularity and reach. As a grammatical form, katsojaa is a routine part of Finnish morphological patterns for agent nouns and case inflection.
