Talk:shell

I don't want to go into changing this without further ado, but are the following not all essentially the same:


 * 1) A hard outside covering, as of a fruit, nut, or animal.
 * 2) A pod.
 * 3) The hard covering of an egg.
 * 4) The hard calcareous or chitinous external covering of mollusks, crustaceans, and some other invertebrates. In some mollusks, as the cuttlefishes, it is internal, or concealed by the mantle. Also, the hard covering of some vertebrates, as the armadillo, the tortoise, and the like.

Is this the following not also the same? You either have an empty shell, in the same sense as all the above, or a live clam, mussel, oyster, etc.


 * 1) Hence, by extension, any mollusks having such a covering.

So all the above could without loss be subsumed in:
 * 1) A hard outside covering, as of some fruits, nuts, eggs, and terrestrial and marine animals.

Perhaps "pod" is different, but is this an example of a shell?

Possible missing noun senses
Chambers 1908 has "the outer ear" (I know we've got a slang ear sense, "a word in your shell", but I wonder if this is something more anatomical), and "an intermediate class in some schools" &mdash; no clue &mdash; archaic educational system? Equinox ◑ 20:02, 18 April 2020 (UTC)
