Infinitive Passive

[Lex]

Pharr lists the infinitive passive of λύω as λυθῆναι or λυθήμεναι. He gives a clue that this is the aorist infinitive passive in another section, but I want verification, since these words don't have the -α-, in place of the thematic -ε-, that seems to be typical of 1st aorists. Thanks in advance.

[edit] Added "1st".

Well, I have to admit that I haven't touched Homeric Greek since the University so I can't say I recall the second form, but the first one is indeed the "standard" passive aorist infinitive. Passive aorist does not have the alpha common in both active and middle voice.

...since these words don't have the -α-, ..

That alpha doesn't betoken any aorists, but only first aorists active and middle, distinct from second and third aorists.

In the passive voice though only the one kind of aorist is found, with the distinctive -θη-.

[IreneY]

Well, if we are getting "technical" -θη- is for the first passive aorist

[Essorant]

That is true. But I prefer to think of the "second" passive as the same type as the first, just showing up without the usual θ of the -θη-.

There is always a certain latitude with passives. I am new to this Forum and am struggling to teach Classical Greek to an adult for a state exam. We are using Greek through Reading and I must prepare several passages for the summer exam for my student. Is there anyone can offer me info about a possible key etc. It would be appreciated very much.
Yours passively....
