|The case of the murder detective|
"At midnight he was set upon in the dark in the bathroom by the bishop armed with a hairdryer, with his friend who had escaped from the cupboard."
The Cluedo Case – or the Clouseau Case.
The ABLATIVE case would have been much used by detectives (had they been around in ancient Rome!) to solve a murder mystery ...
It describes where, when, how, with what, with whom and more.
There are many prepositions which represent this case in English: in, on, at, with, by, from, out of:
The Latin ablative sometimes appears with a Latin preposition, and almost always when a location is mentioned:
coquus in atrio sedet
The cook is sitting in the atrium
When 'with’ means 'in company with' or 'together with', then cum usually appears with the ablative:
coquus in atrio cum domina sedet
The cook is sitting in the atrium with the mistress
But if ‘with’ is describing the manner of something or the instrument or cause, then there is usually no preposition in Latin:
coquus vino ebrius in atrio cum domina sedet
The cook, drunk with wine, is sitting in the atrium with the mistress
