There are metal nuts that twist on threaded bolts;
There are nuts to tighten strings on violins.
There's an "indecent polycarpellary" -
(Sounds like "hissing carp" - but has no fins
It's just a (single-seeded fruit, like hazel- nut).
Now comes the family of nuts we like to eat -
Brazil nut, almond, peanut, walnut, and pecan;
But "nuts to crack" now constitute a mental feat.
A nut may be a drinking cup of coconut,
A tumbler of a gunlock (ally of the fighter);
A pivoted steel piece (or bone) on stock of crossbow. -
Finally, a nut may be a column writer.
