The dictionary I use tells me that Cibus, could mean "food", or "meals" or "dishes", and many other related meanings.
So, I find logical, that, when you have the plural, it means rather meals/dishes.
Translated in the dictionary with something like "I taste dishes"
(the dictionary is not in English, so I re-translated it)
I read some Latin sentences confirming that.
But, I also read Latin sentences implying that it could be used in the singular or in the plural to mean "food". As the French language would use either la nourriture ou les aliments, a singular or a plural, to mean "food" in general.
Admitto aliquid in cibos = here, it's used as food (or it could mean used as "meals" or "lunches", but the meaning would be the same)
It seems difficult to distinguish sometimes when it means food, and when it means meals.
So, could we say that the distinctive meanings between the singular and the plural, sometimes is blurred?
Or is it really, usually, a "rule" that the plural mean rather "meals", etc, rather than the food, taken as a general category?
Could you give me examples of sentences to demonstrate your explanation?
