Metaphorical nomination is peculiar in every language, it is related to reality and world view perception, it also reveals the traits of nation mentality. However, there are universal models of metaphorical nomination. In both languages, special concepts can be nominated according to similar areas, e.g. human body, its physiological and mental peculiarities, mode of life, fauna, flora, objects of natural world, etc.
The aim of this article is to analyse tendencies of metaphorical nominations in IT terminology in English and Lithuanian languages, reveal universalities and peculiarities of metaphorical nomination models. Research data of Lithuanian metaphorical terms and their English equivalents show that semantic loan-words constitute the major part of Lithuanian metaphorical terms. Consequently, their metaphorical meanings are borrowed but a substantial part of them are fairly motivated in the Lithuanian language and only a small part of them have a doubtful motivation. Having analysed various ways of metaphorical transference it is possible to claim that figurative nomination of concepts is the most universal with reference to flora names and items of mode of life. It is noted that there is a tendency to nominate concepts meaning particular objects in both English and Lithuanian languages whereas analogies of abstract things are less abundant.
