FOURTEEN LINES, ONE RHYME SOUND

Someone who sings in synagogue ’s a cantor.
A strident politician is a ranter.
(Not given to frivolity called banter).
A biased fellow you might name a slanter.
A farmer or a bowl is each a planter.
A jogger out of breath will be a panter,
And one who runs around ’s a gallivanter.
Another name for sorcerer is “enchanter,”
And likewise a usurper’s a “supplanter.”
A gent more courteous than you ’s gallanter,
And someone less extinct than you ’s extanter.
The Christmas Elf in Brooklyn they call “Santer.”
But now I’ll go, since rhymes have gotten scanter,
And doff my tasseled cap, my tam o’shanter.
