Hello to all the community,
As a part of my autodidact learning, I am currently studying different kind of Japanese sentences in different situations. For now, I am trying to understand the lyrics of the opening song of the anime Captain Tsubasa (from 1983). More than a translation, I try to figure out the meaning of words and grammar to get a true understanding of the language.
The song I am currently studying is 燃{も}えてヒーロー by Hiroshi Uchiki. I could understand the first sentences by myself and my own researches, yet I am getting quite stuck on the following sentence : それにつけても俺{おれ}たちゃなんなの. This is translated as "Despite that, we are here", but I don't understand from where this comes from...
All I could find about それにつけても is the meaning of "anyways", and this may come from the grammar ...につけ(て), possibly from the verb 付{つ}ける, this grammar having the meaning of "every time I do...", "as soon as I do...". From there, I can't find the relation between 付{つ}ける "to attach, to stuck" and the given translation of "Despite that" or even "anyways". Moreover, 付{つ}ける is a transitive verb and do I don't understand the に particle here, targeting それ. Maybe am I seeding from the wrong verb ?
I am also in trouble for the second part of the sentence : 俺{おれ}たちゃなんなの, translated as "we are here". If I could figure out that 俺たちゃ is a plain and spoken way of saying 俺たち "we, us", the なんなの part gets me confused. Here I guess we have 何なの, a shortened form of 何なのですか, meaning "what is it", with a certain emphasis or interest towards the question. So if I get all altogether, I may try a rough translation of "what are we ?" (probably in the meaning of "what do we represent in this world ?"
Overall I get for それにつけても俺{おれ}たちゃなんなの a translation of "Anyways, what do we represent in this world ?" which is very far from the declarative "Despite that, we are here".
Does anyone have a better understanding of this ? To get the sentence in context, we can use this website.
Please forgive me if the question is not properly asked, as I am not English native, which is a language that I am also currently studying.
Thank you in advance for your precious help !
