Being particular about names points to the sense of language that is characteristic to all of Kalju Kruusa's poetry. Yet, his poems deal mainly with the down-to-earth aspects of everyday life, and even touch upon private life – in spite of playing hide-and-seek with the reader.
Kalju Kruusa entered the Estonian literary field in the 1990s among the line-up of the young writers' group Erakkond ['Hermit-kind'. A newly-coined word resembling, and opposing, the word erakond – meaning '(political) party']. The group also comprised of Kristiina Ehin, Mehis Heinsaar, Aare Pilv, Lauri Sommer, and others.
Kalju Kruusa (born in 1973 in Tallinn, Estonia) is a poet who claims to ''never wear plainclothes'' as a writer. Even the name Kalju Kruusa is but a pen-name (a small poem in itself, as noted by critics, with Kalju meaning 'Rocky, Cliff, Craig, ' and Kruusa meaning 'Pebbles, Shingle, Scree') .
