cosa
"Cosa" is not a Swedish word; it is Spanish, meaning "thing" or "object."
In this sentence, 'cosa' is used informally to denote an object or matter whose name or nature is not specified, often conveying a sense of ambiguity.
Vad är det som händer med denna konstiga cosa?
What is happening with this strange thing?
Here, 'cosa' refers to a minor object or item, implying familiarity or informality in describing a non-specific physical item.
Kan du ge mig den lilla cosa som ligger där borta?
Can you give me the little thing that is lying over there?
In this case, 'cosa' is pluralized (cosas) to indicate various items or entities, again used informally for referencing multiple unspecified subjects.
