It aims at complementing other empirical studies which merely focus on differences between British and American English or which investigate the alternation of the Present Perfect with other timereference forms. Findings are based on material from the International Corpus of English (ICE), which has been annotated for various language-internal factors (such as semantics, preceding tense, etc.), so that the distributions and the relative importance of these factors can be analyzed. I employ explorative aggregative methods to find measures of similarity between the various varieties of English under investigation. In addition, this approach allows a systematic investigation of the influence of language-external variables (such as text types, variety types, geographical location) across all varieties. Furthermore, a case study on evidence of an allegedly extended functional range of the Present Perfect in terms of tenselike usage is presented. The data reveal (i) that the Present Perfect can be seen as a globalized or core feature of world-wide varieties of English, and (ii) that geographical location, variety types, mode of discourse, genres and text types only have a weak effect when associations between varieties are explored; significant groupings across all varieties appear along register lines, however. The case study shows that creative usage in terms of a functional extension of the Present Perfect occurs in the ICE data, albeit largely restricted to informal speech in L1 varieties and to L2 varieties, where influence from both the substrate and through learner language is highly likely. The case study further exemplifies layering between the Present Perfect and its competitor, the Simple Past, in indefinite temporal environments.engpresent perfectsimple pastInternational Corpus of Englishaggregative analysisregister420bookpart10.1515/9783110429657-005https://opus4.kobv.de/opus4-bamberg/frontdoor/index/index/docId/50209
