• sweeping curtsy

• deep voice

• treacle sleep

• dead secret

• low

• dead faint

• deep bass

• low neck

• dead asleep

• in deep mourning

• dead faint

• communion

• sweeping curtsy

• to plough

• high respect, homage

• to bass

• to get beyond one's depth, to get out of one's depth, to go beyond one's depth, to go out of one's depth

• soundless

• scoop neckline

• to talk in one's boots

• whoop
