Let's assume the -be' applies only to the -laH. Not able, resume, eat. This might mean we resume being not able to eat
maSopqa'laH means we are able to resume eating or we resume being able to eat.

So, if I understand correctly, one of the possible interpretations of
the word {maSopqa'laHbe'} is with the suffix {-qa'} acting solely on
the suffix {-laH}. Right ?

You're trying to draw me into saying something stronger than I intend it. -qa' doesn't act solely on -laH. The word as a whole has the subject resuming something and the subject being able (or not) to do something. Canon shows us that it's not always as simple as applying each non-rover suffix only to the root verb, and it's not always possible to see each suffix as applying to the entirety of what came before it. At some point you have to see that Klingon doesn't get as precise as that. It's not like a computer program following an exact sequence of steps to evaluate an expression to a single return value.

paq'batlh has a line, chaq batlh bIvangqa'laH You might have a chance to make amends. Literally, it means You can take action honorably again. Or does it mean You again can take action honorably? Or does it mean You can honorably take action again? More importantly, does it even matter? Is not the idea expressed anyway? It certainly makes all kinds of sense in the paq'batlh, where Kahless's brother Morath realizes he was wrong to fight Kahless and Kahless says this to him in forgiveness.

Here's another: tlhInganpu' tlhabqa'moHmeH [to make the Klingon people] self-sufficient once more, literally in order to cause Klingons to be free again. Or is it in order to again cause Klingons to be free? (The idea behind this line is that the Klingon people themselves will make the Klingon people free once more, so what they did once the could do again.) Again: does it matter? You end up in the same place, and the context makes the meaning unquestionable.

I really think you need to back off of these super-precise analyses. You're dropping below the resolution of the language.
