The present perfect and definite past time adverbials

What is it about?

English normally distinguishes between the present perfect and the simple past: we say I have seen him but I saw him yesterday. Yet speakers sometimes use the present perfect with expressions such as yesterday, last week, or twenty years ago, even though these combinations are traditionally considered unacceptable. This study examines how and why such unusual uses occur in British and American English. Using data from the British National Corpus and the Corpus of Contemporary American English, it shows that these forms are rare but far from random. They occur especially in spontaneous speech and other contexts where a past event is still important to the conversation. The study proposes that the present perfect can sometimes serve as a kind of “shortcut”: it locates an event in the past while at the same time signalling why that event matters to the current discussion. This “relevance compression” helps speakers keep a topic in focus without having to spell out the connection between the past event and the present situation. The comparison also reveals differences between British and American English. American English contains more contexts in which the present perfect can be interpreted both as expressing present relevance and as referring simply to a completed past event. These patterns suggest that the boundary between the present perfect and the simple past is more flexible in actual usage than traditional grammatical descriptions imply.

Why is it important?

Our findings show that the English present perfect, though canonically restricted from co-occurring with definite past adverbials such as yesterday, last week, and ago, nonetheless does so systematically, especially in spontaneous discourse. We term this strategy “relevance compression”: a single verb form that fuses past temporal anchoring with current relevance, thereby keeping discourse topics coherent and economical. The same form also serves a temporal gap-bridging function, allowing more remote past events to remain salient in the ongoing conversation and found even in academic discourse. This is timely because it supplies new corpus evidence, drawn from the BNC and COCA, on a long-debated puzzle in tense-aspect research at a moment when scholars are tracking possible aoristic drift in varieties of English. Rather than treating these non-standard uses as errors or as clear evidence of semantic change, the study demonstrates that they constitute a stable, genre- and register-conditioned pragmatic strategy — more frequent and more widely distributed across genres in American English than in British English.
