Swedish doesn't have a direct equivalent to the English continuous "-ing" form (like "is working" or "are reading"). Usually, the simple present tense is enough. However, to emphasize that an action is ongoing right now, Swedish often uses a structure called pseudo-coordination.
This involves pairing a positional verb with och (and) and your main active verb. If the person is on their feet while doing the action, use står (stands). If they are seated, use sitter (sits).
While this translates literally to "stands and digs" or "sits and enjoys", it is the natural Swedish way to say "is digging" or "is enjoying".
Where to put adverbs
When using sentence adverbs like ofta (often), aldrig (never), or ju (of course), place them immediately after the first verb (the positional verb).
Lying down
Naturally, if the subject is lying down while doing the action, use ligger (lies).
Describing busy scenes
You will often see these positional phrases combined to set a scene with multiple ongoing actions, frequently connected by words like medan (while).
