1107: The Number of All and Every Dec 20, 2017

The words 'all' each and 'every' are often interchangeable semantically, except that 'all' is used as to describe quality, such as "all right", as well as many other nuances. Moreover, 'every' and 'each' may have generally the same meaning of uniting a group as 'all' does, but grammatically they are not often treated the same, and instead they skew more towards only singular than 'all' would skews towards the plural. One could say "all men [plural] are dogs" but that would likely become "every man [singular] is a dog", for example. It is easier to use 'all' in singular settings such as "all food [singular] is expensive" or "all foods [plural] are expensive", which does not work as often with 'every'. There are exceptions of course, such as "trains leave every 2 minutes [plural]". Even more than 'every', 'each' almost never would be used with the plural.
