note

Countable: one eggshell, many eggshells; also written as two words, «egg shell», but «eggshell» is more usual. Fun science fact: an eggshell is hard to crush when you squeeze it from both ends, because the dome shape spreads the push; it breaks easily on an edge. «Walking on eggshells» is an idiom, not about real eggs.

In the corpora

• The colour of an eggshell depends on the hen's breed, not on how healthy the egg is.
