Etymology: "Shielder" is a plain formation: the noun "shield" with the agent suffix "-er," meaning one who does the action or fills the role. The shield itself is one of the oldest defensive tools in English, so the word simply names the person or thing that carries out that protective job. The base word "shield" traces back to Old English "scield," and the suffix "-er" has been used in English for centuries to turn verbs and nouns into names for people or things that perform an action, as in "baker" or "teacher." Combining the two gives a transparent word that needs little decoding: one who shields. The source traces the form back to Middle English "schildere," which the same "shield" plus "-er" construction produced. Its meaning stayed close to the literal idea of a physical guard, extended over time to cover anything that acts as a safeguard, such as a person standing between another and danger or a device that blocks harm.
