My flashcard deck has 2 very similar cards:
- meaning: to load, pile up
- jisho.org: to pile up; to stack
- meaning: to place on, load onto, draufstellen
- jisho.org: to place on (something), to load (luggage); to carry; to take on board
As a non-native of either English or Japanese, I don't see the difference. I feel like 積む is for big objects and a rough action, while with 載せる the loader is concerned about the final position of a rather small object. But I have too little evidence.
So when I put an object on another object, when would I use the first and when the second?
