Beyond the definition
Just as steel hardens when cooled, things can "harden" in many ways – physically becoming more solid, or emotionally becoming less sensitive. Wet clay may harden in the sun, while a difficult experience could harden someone's heart.
Think of chocolate: it starts soft but hardens when refrigerated. Or consider a soldier who has seen battle; those experiences may harden them to the realities of war. "Harden" can also mean to make something more resistant – like hardening steel to make it stronger. It's about becoming stronger, more unyielding, or less flexible.
To harden means to become firm, rigid, or solid. This can apply literally to physical materials—like when clay hardens in the sun, or cement hardens as it dries. "The blacksmith hardened the sword by plunging it into cold water." It implies a change in state from something pliable or soft to something more durable and resistant.
However, "harden" isn't limited to the physical world. It can also describe an emotional or psychological shift. Someone who experiences hardship might harden over time, becoming less sensitive or empathetic as a defense mechanism. "Years of betrayal had hardened her heart." This doesn't necessarily mean they are cruel, but that they have built up defenses against further pain.
You can also use "harden" to describe making something stronger or more resistant. For example, you might harden security measures after a break-in, or harden your resolve when facing a difficult challenge.
The word carries a sense of becoming fixed and unyielding – whether it's the firmness of stone, the resilience of a spirit, or the strength of a defense. So, if something is hardening, it's becoming more solid, resolute, or resistant to change.
