Latin 101
PIP - 3rd & 4th Conjugation
Formation:
1. Find the stem:
- tangö, tangere, tetigï, täctum: -> tang-
- rapiö, rapere, rapuï, raptum -> rapi
- sciö, scïre, scïvï, scïtum -> scï
[if the stems for 3rd conjugation and 3rd i-stem's are troubling you, review Chapters 8 & 10]
2. add endings:
or mur eris minï tur [u]ntur
nb: the 2s form is "e" not "i" for 3rd conjugations and 3rd i-stems. For the 4th conjugation, it will follow the paradigm [ïris].
Paradigms:
| tangö, tangere, tetigï, täctum | sciö, scïre, scïvï, scïtum | rapiö, rapere, rapuï, raptum | |
| 1S | tangor | scior | rapior |
| 2S | tangeris | scïris | raperis |
| 3S | tangitur | scïtur | rapitur |
| 1P | tangimur | scïmur | rapimur |
| 2P | tangiminï | scïminï | rapiminï |
| 3P | tanguntur | sciuntur | rapiuntur |
Infinitives:
4 conjugation verbs [e.g., sciö] form their passive infinitives by changing the last letter of the 2nd principal part [the present active infinive] to "ï" -> scïre -> scïrï
3rd and 3rd i-stems had to be different. They drop the "ere" of the infinitive" and add "ï"
tangere -> tangï ....... rapere -> rapï
Shall we drill the PIP? [That's a rhetorical question.]
