This diploma thesis deals with time metaphors in English, German and Croatian. A corpus of 500 entries for each language was used to establish the similarities and differences between the aforementioned languages in terms of time metaphors. In addition to the linguistic aspect of the concept of time, other aspects were discussed briefly. Time, as the central topic of this thesis, was defined as a cultural construct. It is, however, of great importance to the human world, which is visible in languages throughout the world, due to their devices for expressing various aspects of time. I have compiled a corpus for German, the tables and results of the study conducted by Omazić and Schmidt were adopted for English and Croatian. The corpus-based study was conducted following the same methodology as Omazić and Schmidt did and the results are presented in the same way. According to the results of the corpus-based study, these three languages (two Germanic and one Slavic) exhibit striking similarities in terms of time metaphors.
