this is interesting to think abt, bc when adapting comics into animation for example, onomatopoeia are added in some places, because they look fun and remind the viewer of the comic roots, even if a sfx is also there. onomatopoeia I've always thought of as "the visual effect written as that sound"

tho imo, if I look at local comics in estonia, it seems artists don't use these as much unless they have more western influences - onomatopoeia itself as a word seems so foreign, I find people just mix them up with the meaning of sound effect or "extra effects" bc they're not used much
