can have several different meanings in Japanese, depending on which part of the sentence it is in, and what comes before/after it. It is often translated as ‘from’. In these cases, it just means ‘with (A) as a starting location, (B)’. In this grammar construction, から
comes directly after the place that is considered the starting point.
This form of から
is the closest to the ‘base’ meaning of the word in Japanese, as the nuance of から
can almost always be thought of as meaning ‘from’ in some way.
This form of から does not require だ when used after nouns or な-Adjectives, as that would change the meaning to ‘because’.
