The aim of the article is to present an analysis of variant endings -i and -é. The research was carried out on the base of Czech National Corpus SYN2005. The ending -i is a variant of ending -é in the standard language (it amounts to 4 %). According to the corpora examination, the ending -i can be mainly found in the names of followers and members of social and political movements and institutions. No occurence or sporadic occurrence of the ending -i can be found in names of followers of religious views, suppor-ters of religious movements and members of sects, the names of specialists and sportsmen. The occurence of the form -i depends on the various factors: linguistical layer, semantical group that the word belongs to, type and frequency of the word, context and a text.
