Would someone be so kind to explain me what the bold part means in this sentence:
"Yes, but the word has dropped out of the text, or perhaps was subauditum; that is, present in the king's mind, but not uttered," said Mr. Casaubon, smiling and bending his head towards Celia, who immediately dropped backward a little, because she could not bear Mr. Casaubon to blink at her.
