This article is devoted to tabooing of words of a theme group "religion" in so called folklore poems of M. Tsvetaeva. They are meant as the poems written on national plots ("Molodets", "Tsar-Devitsa", "Pereulochki", "Egorushka"). Folklore basis of these poems does lawful an integrated approach to studying of taboo-words and allows to consider them as archaic. Works in the field of ethnography, folklore, ethnolinguistics, modern Russian, etc. are attracted as a scientific basis. Researching of words of a theme group "religion" supplements the analysis of verbal tabooing undertaken by the author in 2007 on the example of other theme groups ("evil spirits", "death", "names", "people", "food", etc.). Methods of interpretation of the art text and linguistic material, the semantic, phonetic and structural analysis, comparison, description and also a comparative-historical method are applied. The analysis and the description of tabooing of the words in archaic and modern (etiquette) forms in a poetic idiolect of M. Tsvetaeva, allocation of traditional lines of a taboo and euphemisms and their author's features, their semantic and structural classification are the main goal of the largescale scientific work. Semantically taboos of a theme group "religion" are allocated for words and phrases God, the Virgin, an angel, hell, paradise, a sin (adultery), the apostle Pyotr, amen. Tabooing of these words is traditional, but isn't realized by modern native speakers as the ban. Euphemistic replacements are the main form of verbal tabooing. Selection of euphemisms is based on the ideas of appearance of images, their functions, the spatial characteristic of the phenomena, general for Christian and national consciousness. Tabooing is carried out by the way of unfinished word once. This unfinished word is caused not only semantic, but also by plot that is a characteristic of the untold words in folklore poems of M. Tsvetaeva. Functions of euphemisms of this theme group are reflection of national ideas of the main Christian concepts, about a peace arrangement and underlining of a folklore basis of poems of M. Tsvetaeva.
