The Idiotisms and Proverbs section is one of the more hilarious and I wonder how many of them can be mapped back to originals. The only one I could trace is A horse baared don't look him the tooth , which presumably maps back to Don't look a gift horse in the mouth . Probably quite a few of them are no longer common in English either by now, which makes computing the inverse harder.
I could decode these, because there are equivalents in my native Russian: >"With tongue one go to Roma" = you can achieve anything with good communication skills >"It want to beat the iron during it is hot" = seize the opportunity while you can >"to come back to their muttons" you say "let's go back to our sheep" when you realize you digressed
“Strike while the iron is hot” is a well known English saying as well. Guess blacksmith wisdom is universal.
