Last year, we asked our readers what words best describe their mothers. We noticed a prominent theme in the terms, which spoke of moms most "tenacious," "resilient," "indestructible," and "unyielding" in character. One submission effectively encapsulates this theme: strong. This versatile adjective entered English over a thousand years ago as a descriptor of physical power and muscular force. Shortly thereafter, it took on a meaning of great moral power or courage. Since then, senses and applications for this term have multiplied, giving us variations such as “powerful in influence or authority” and “able to resist strain, force, wear, etc.” Sound like anyone you know?
