The pronunciation \ˈgit\ has been noted as a feature of some British and American dialects since the 16th century. In the phonetic spelling of his own speech Benjamin Franklin records git. However, since at least 1687 some grammarians and teachers have disapproved this pronunciation. It nonetheless remains in widespread and unpredictable use in many dialects, often, but not exclusively, when get is a passive auxiliary (as in get married) or an imperative (as in get up!).
