The meaning of を as I heard from Youtube's Takanori Tomita

[Janet Merai]

Takanori Tomita's podcasting had me curios about a certain Hiragana character's usage in one of his podcasting videos.

Is "（w）o / を" really used for conjunctions like:

おすしをたべます - I eat Sushi
おすしをたべました - I ate Sushi

Here is his video:



Are they really good to use for conjunctions and not wa?

I kind of see the difference now, I was confused in the beginning about the usage of "(w)o" before-hand.

You'd better to learn first what the PARTICLE is, imo.

I wouldnt really call this a conjunction per se...certainly it's function compared to "wa" is very different. "wo" typically marks the object of a direct verb. Like in your example of Taberu/Tabemashita. The particle "wo" indicates that it is the sushi being eaten.

"Wa" typically marks the "topic" or "subject" of the sentence.

Janet-san wa sushi wo tabemashita.

Janet ate sushi.

Thank you so much people!
This brings me one step further to understanding the language!

I would say that the only vestiges of を's old use as a conjunction (meaning something like "although") is in the conjunction ものを, which usually ends up getting used at the end of utterances in my experience. Ex. 昨日豆乳を買ってきてよかったものを。(~"If I had only bought soy milk yesterday"). It's very similar to のに but more restricted in its use. If any native speakers could weigh in on this it would be appreciated (the memory's a bit fuzzy).

Otherwise, like Toritoribe said, it's a particle.

Probably, ものを in the sentence end is mainly used with "the conditional form + いい/よかった", something like すればいいものを/よかったものを, したらいいものを/よかったものを. Thus, ものを can be basically replaced with のに, the reverse is not always so.

○昨日豆乳を買っておきさえすればよかったものを。
○昨日豆乳を買っておきさえすればよかったのに。

○運動会でまたビリだった。一生懸命走ったのに。
×運動会でまたビリだった。一生懸命走ったものを。
("一生懸命走った" is the certain fact.)

「のに」は確定条件の逆接にも仮定条件の逆接にも使え るけど、「ものを」は主に(英語の仮定法のように)仮定 条件の逆接に使う、という感じがしますね。あまり自信 はないですが。
