This research examines the possibility of epicentral influence of AusE on NZE, focusing on morphosyntactic variation over 170 years in verb inflections (-ed/-t) for the past tense/participles of a set of 12 verbs including burn, learn, spell, spoil. To obtain a diachronic perspective on them in Australasian Englishes we use historical data from 19th- and 20th-century corpora, and 21st-century data from the NOW corpus of online news. Most verbs show increasing use of -t forms in AusE from the 19th to 20th century, and an increase in NZE in the later 20th century, which could be construed as epicentral influence from west to east. But in 21st-century data from NOW, the -ed/-t balance shifts to -ed in both Australasian varieties for eight out of 12 verbs. The fact that -t usage on some remains higher in contemporary NZE than AusE suggests a kind of epicentral lag.

1850-2020 年澳大拉西亚英语中 -ed/-t 屈折变化的震中效应

这项研究检验了 AusE 对 NZE 的震中影响的可能性，重点研究了 170 年来动词变位（-ed / -t）的形态句法变化，用于 12 个动词的过去时/分词，包括烧、学习、拼写、破坏. 为了在澳大利亚英语中获得对它们的历时视角，我们使用了 19 世纪和 20 世纪语料库的历史数据，以及 NOW 在线新闻语料库的 21 世纪数据。大多数动词显示越来越多地使用-t从 19 世纪到 20 世纪在 AusE 中形成，20 世纪后期 NZE 增加，这可以解释为从西向东的震中影响。但在来自 NOW 的 21 世纪数据中，12 个动词中有 8 个的-ed / -t平衡在两个澳大利亚变体中转移到-ed 。在当代 NZE 中， -t对某些人的使用仍然高于 AusE，这一事实表明存在一种震中滞后。
