386 of the most frequently used irregular verbs in the Latin language with all four principal parts. These ver...bs belong to the 4th Conjugation: (blandior, blandiri, blanditus sum). Note that these verbs are passive in form but active in sense. Note also that the verb ORIOR, ORIRI, ORTUS SUM was very frequently conjugated by Romans as a 3rd and not a 4th conjugation verb. Thus the accent fell on the first syllable and not on the second syllable of ORITUR. As you will hear, I have decided again to go against convention and not include the final "sum" for the third principal part. Just remember to add it mentally yourself.
