から

Word から can be found easily in any daily or formal conversation. There have two meaning so far I know, that is 'because' and 'from'. The meaning selection depend on から location itself. So, if から is before a comma (,), it means 'because'.
I give you and example:

眠れない(ねむれない)  から、疲れているよ(つかれているよ)
Because I can not sleep, I'm tired!




Another meaning of から is used to show time or location which is it should be use together with まで. Example:


学校(がっこう)  は  8時(じ)  から  2時  まで  です
School is from 8.00 until 2.00


アメリカ  から  日本  まで  行きます(いきます)
I will go from America to Japan




In third example, there have no subject marker (word that highlight with particle 'は' . If you see sentences like this subject marker is a speaker himself (I).
