I don't understand the function of もの in the following sentence:
薬がものすごく苦かったから、急いで飲み込んだ。
The sentence makes perfect sense if I omit もの altogether, and I am not sure what is its function in the sentence. Could it be a typo?
薬が
ものすごく苦かったから、急いで飲み込んだ。
The medicine was so bitter that I swallowed it swiftly.
