I came across the word 広がってきています. The sentence is
I believe this is the verb 広がる, to spread, in its て-form plus the continuous form of 来る. Is that right?
So, if this is the case, what is the meaning of 広がってきています? I thought this form was used to describe the action of doing something and then returning. Like 食べてきました, I went and ate (and then came back). This motion suffix related to a trend is a bit confusing to me.
Thank you very much.
