Tread Lightly and Carry a Big Word

Books about one word 
Are treacherous, to the extreme
Presuming listener heard
The decorous letters fill reams

Argue one may
With the fountain pen
Trailing beyond days
Encounters with diagrams Venn

Futures loft the past
Over shoulders by paragraph
Watchwords doff caps
Bygone soldiers fight wrath

Containers ship product
Ignorance in bulk
Trained to cast muck
Phrase defensive sulk
