Lesson XV - Primary Tenses Question

[fjamespar]

I cannot figure out what the primary tenses are for. Are they similar to reflexive verbs in spanish, where the suffix describes the person to whom the action is taken? If so, then "lelukasi" would mean "I have broken them"?

Is this correct, or am I way off?

If you go to page 27, 110 Paradgms, FIRST PERFECT at the bottom you will see λελυκασι they have loosed. I am no Ancient Greek scholar, but in Latin, the primary tenses are - (simple present tense, present perfect, simple future tense, or future perfect). If this is the same in greek, it just appears that they are the simple tenses. I have a textized copy of First Greek Book, (downloadable on my tachufind website by the way) so it is searchable, First Greek Book does not appear to explain this, I was unable to find any good description in the book.
