What’s going on? Words like every and some, as well as others like a/an, a few, several, much, many, a lot of, most, any, each, all, and so on are known as quantifiers, and the relationship between them is known as scope. Whenever you have more than one quantifier in a sentence, you have the potential for their scopes to interact with each other in multiple ways, creating several different possible interpretations for the sentence, a phenomenon known as quantifier scope ambiguity (or more generally just scopal ambiguity).
In most cases, we interpret potentially-ambiguous sentences without problems based on our knowledge of the world; however, particularly if you’re writing without a lot of context or in a reduced style such as a headline, you may want to double-check or get someone to read over your work to make sure you’re not saying something you didn’t intend!
Alternatively, if you’re considering a career as a comedian, ambiguities like this can be a great way of subverting people’s expectations and thereby creating humor.
