filled the interim

Source: from Wuthering Heights (1847) by Emily Brontë (chapter 13)

Context: At Wuthering Heights Isabella felt miserable. She had hoped to find a friend to support her against Heathcliff. Once there, she soon realised that nobody would help her. She had left behind the only people she loved in the world, for a house where that feeling didn’t exist.

I listened to detect a woman’s voice in the house, and filled the interim with wild regrets, and dismal anticipations, which, at last, spoke audibly in irrepressible sighing and weeping.

This is another passage I’m struggling with. I can’t grasp the meaning of a couple of phrases, such as “filled the interim” and “spoke audibly”. If anyone could help it would be greatly appreciated.

Thanks a lot

I listened to detect a woman’s voice in the house,

and filled the interim with wild regrets, and dismal anticipations,
= and, while waiting, found myself indulging in wild regrets and dismal anticipations,

which, at last, spoke audibly in irrepressible sighing and weeping.
= which eventually could be heard, as they turned into irrepressible sighing and weeping.

How easy it is with a brilliant native speaker by your side! It always is!
You could be Nelly Dean, the narrator, I could be Mr Lockwood writing down what happened to Heathcliff and Catherine. Then you could help me reword the whole story. What do you say? 👁 Big Grin :D


Thank you so much lingobingo
