>PIE has only two tenses, present and preterite (past). Oddly enough, it is the present tense that is overtly signalled by obligatory morphological markers. Since a regular present/preterite contrast is clearly evidenced for the durative aspect only, it is likely that 'past-tense' verbs were originally used without particular time reference, and did not acquire a distinctively preterite meaning until the development of specially marked 'present continuous' forms.

>The morphologically simpler preterite endings are called 'secondary', while the present endings (usually involving the present-tense marker *-i) are called 'primary'. These traditional terms are rather confusing, and I'm in favour of avoiding them.
