doorsill

The preacher must hold their hands until they cross the doorsill of the Audience Chamber.

And as I looked on, through the crevice under the doorsill, he put out his free hand and with his finger touched the woman gently.

Its doorsill lay even with the pavement, inviting custom by an easy access, while repelling it by its squalor.

Then and then only, during all that time of watching, did Lad leave the doorsill of his own accord.
