Words to express relations of the context of before and after as connective words alone. An independent word. It does not inflect. It is distinguished from the connective particle (I am unpleasant, equal) that is an adjunct (connected to the verbs).
The conjunction is one of the parts of speech to carry a role to show relations between items such as a sentence and a sentence, a knob and a knob, a phrase and a phrase, a word and a word in on in the English. The English conjunction is divided into a co-ordinating conjunction and a subordinate conjunction to give below. In addition, in this item, I speak conjunctive adverb (however) as a thing taking a role to be similar to a conjunction not a conjunction as well as these inherently although it is an adverb.
A conjunction has usage, and there are a thing (negation sentences do not come after before in principle) and the rule of a place (but does not come in principle in the beginning of a sentence) come to connected by each conjunction every each word although some type is possible.
In addition, there is the case which can be distinguished with a preposition and the relative when I translate it into Japanese and thought. In the first place there is the word with both uses of the conjunction / preposition, too. It is said that these points are made questions for by the English examinations such as the TOEIC well.
A co-ordinating conjunction is a conjunction to connect a word, a phrase and a phrase, a sentence and a sentence to a word by equal relations. On the idea that "the equal relations" to say here are not the meaning top and equality on the tense, and independent each, which item which is merely connected can form a meaning equally. I call a sentence a compound sentence from plural equal passages connected by a co-ordinating conjunction in this way.
