Just a question...
Why "palmas" and not "manus"?

I think both are fine, Alex. But I can change it into 'manus' if you want.

Oh, you didn't need to change it if it was fine.
I just wanted to know if there was a difference between the two nouns (since their Italian descendants "mano" and "palma" don't mean the same thing).

Dear Alex,
Of course “palma” and “manus” do mean slightly different things in Latin too:

palma = palm, hand; blade…
manus = hand (but also: corps, band, company, power…)

However they sometimes have got the same meaning and may replace each other, especially when some phrases are concerned, e.g.
-palmis suspensis/ manibus suspensis (with hands raised)
-habens palmas/manus in coelum erectas (having hands erected towards heavens),
-palmis/manibus capere (to catch, to seize with hands) etc.

Hope I was clear enough.

Yes, you were. Thank you for your accurate explanation

I have a doubt about "pro+ablativus".
Isn't "ad futurum carpendum" better to translate a final clause?

Yes, you're right that "ad" is better.
(Pro + abl is a bit Medieval construction "Pro discendo. Pro vivendo"- For learning. For living).
Thank you!
