Dog-Latin
Meaning: The vocabulary and grammar of Latin spoken and written from the end of the Roman Empire until medieval times (at which point, in theory, Church Latin prevailed); but also the sort of Latin spoken and written by people from that time until today who have not been taught properly or who are not good at it anyway (or who try simply to “latinize” English words)
Origins & History: The expression in English was first recorded in 1611 and is one of those in which the word dog implies “less than real”
