In sentences like
２時ごろ子どもを迎えに行きます。I will go to meet/greet my child around 2 O'clock.
Is the sentence structure of verb(Stem form)に行く/来る/帰る, ever strictly necessary? Or following the example, would
２時ごろ子どもを迎えます。I will meet/greet my child around 2 O'clock.
be sufficient. In other words, is the fact that you will go somewhere to do this action already implied (in some cases).
来月旅行に行きます。I will go travel next month. VS. 来月旅行します。I will travel next month.
Aside: I can see how in examples like
映画を見に行きたいです。I want to go see a film.
The format it's written in would be useful, as the emphasis is placed on the fact that you wish to go somewhere to see a film, not simply that you want to watch a film.
Thank you for, any and all, help! Much appreciated!
