Step-by-step explanation:
In Latin, quo loco refers to the ablative case. The ablative case is used to indicate various meanings, such as the location where an action takes place, the means by which something is done, or the manner in which an action occurs. It is also used after certain prepositions.
For example, in the sentence 'Romae sum.' ('I am in Rome.'), Romae is in the ablative case to indicate the location.
Other prepositions that require the ablative case include ex ('out of'), pro ('in front of'), and sine ('without'), among others.
