Q, I'm intrigued with many (maybe I should only say "several") of the items in your lists, the translations of which are so detailed or special that they might only be used on a particular occasion, or perhaps by a particular individual. Such as, for a couple of examples:

Rutaceous- Reserve for myself and wife a good suite of rooms
Titmouse- I accept with pleasure your invitation for the theater tomorrow evening

I understand the utility of a list of "building blocks" for messages, but why would one assign a special code word for a likely one-time use?
