More Greek-based verbs: past participle

Now I mentioned a way to add Greek verbs into the mix a few posts ago. Now, the verbs derived from Latin have four principle parts that I intend users will memorize: the imperfect, the infinitive, the perfect, and the passive participle. I've only mentioned my thoughts concerning the indicative and the perfect forms (which are by no means set), but I wanted to mention also the passive participle which can be derived directly from the Greek present perfect participle.

Compare the four principle parts of:

the Greek-origin verb "to stop:" pavo, pavere, epausi (or pepauci), and pavomena/o

the Latin-origin verb "to love:" amo, amare, amavi, and amata/o
