The present article aims at summarizing the results of the corpus-based study of the semanto-syntactic behaviour of the emotionally-loaded Polish adverb niestety ‘unfortunately/regrettably’. It will be claimed that the different uses of niestety are governed by the processes of subjectification, both at the synchronic and diachronic level. Such a perspective also allows us to explain the intersubjective senses in which this highly grammaticalized adverb is sometimes used in Polish.
