A specific term (khass) is assigned a determinate meaning, whether referring to an individual, a species, or a genus. A general term (amm) includes multiple members within its scope. The distinction concerns designation and inclusion, not the number of words.
“Three” determines a particular number and illustrates specificity. “Every” indicates comprehensive coverage within a specified domain. Nor should one confuse generality over members with the unrestricted selection of one unspecified member.
