I am trying to understand the role of するって and its meaning. Taking the phrase:

24じかんこうどう ともに するって こういうこと

I can't give a meaning to it. Any help?

((24じかんこうどう ともに する) って) こういうこと. Does it make sense now that I split things up like this? – nhahtdh Jan 12 '14 at 18:32
I think now i understand. It becomes "I share these things from 24 hours" i guess, right? – Antonio Verlotta Jan 12 '14 at 18:47
"on a mission" is pretty bad as a translation of 行動. I take the text to be this: 24時間行動 共に するって こういうこと. When you said "doing an activity together for 24 hours, this is what you mean" – virmaior Jan 12 '14 at 22:34
I think it's parsed as 「『24[時間]{じかん}、[行動]{こうどう}*を*ともにする』って、こういうこと」, i.e. 「『24時間のあいだ、[一緒]{いっしょ}に[行動]{こうどう}する』とは、こういうこと(+か。/だ。etc.)」 – user1016 Jan 13 '14 at 6:05
(I mean, 24時間行動 is not a noun phrase, but the 24時間 modifies the ともにする adverbially.) – user1016 Jan 13 '14 at 6:24

って = というのは

「って」 is an informal topic marker that is frequently used in casual conversations.


「Aって、こういうこと(だ)。」 = "This is what A means."

A = Spending 24 hours with someone / Being with someone at all times
