I am pleased to learn that “astonish” does not derive from a word meaning “turn to stone”, but from extonare (Latin), to be thunderstruck.

• 03.009 Bilbo was astonished.
• 03.020 “Most astonishing wonderful!”
• 04.048 in their astonished eyes.
• 06.014 Gandalf was as astonished as any of them,
• 08.118 and to the great astonishment of the dwarves he vanished.
• 08.121 and charged into the astonished spiders
• 10.018 Their astonishment was enormous
• 10.037 amid scenes of astonishing enthusiasm.
