Let us learn one of conjunctive particle “-to,”. At first, what is the difference between a conjunctive particle and a conjunction?
[ Dependent Clause ] + < Conjunctive Particle >, [ Main Clause ].
[ Sentence1 ]. <Conjunction>, [ Sentence2 ].
A conjunctive particle is attached to the end of a dependent clause, so that the main clause of a sentence can be placed after the dependent clause. The particle “to” has already introduces as a case particle as below;
– Tomodachi to Ryokou ni Ikimasu. (I am going to travel with my friend.) — A3 S5
– Ashitano Tenki wa Yoku naranai to Omoimasu. (I don’t think weather gets good tomorrow.) — A1-3 S21
But now what we are learning is “-to,” which is a conjunctive particle. Look at the following examples;
1. Okane o Ireru to, Kippu ga Dete Kimasu. (Putting your money in, a ticket is coming out.)
2. Kono Botan o Osu to, Heya ga Akaruku Narimasu. (Pushing this button, the room gets brighter.)
3. Migi e Magaru to, Pan-ya ga Arimasu. (Turn right, then you will find a bakery.)
These sentences have the construction of;
[Clause A] + to, [Clause B].
When A happens, and then B is caused by A. In the cases of sentences 1 and 2, the machines are designed to make Action A cause Action B. Taking the action A is hypothetical, but once A happens, B will almost certainly occur. Therefore, Clause B must end assertively.
Good : Natsu ni Naru to, Atsuku Narimasu. (When summer comes, it gets hot.)
Bad : Natsu ni Naru to, Isshoni Umi e Ikimashou. (WRONG: Come summer, go to the sea together.)
A sentence using the conjunctive particle “to” should not end with expressions of will, invitation, command and so on.
