覚え方のコツ Memory Tip
まず基準語 cathode（陰極）を固め、その形容詞版が cathodic と覚える。-ic は「〜に関する」という理系語で、anode → anodic と同じ型。電池・電気化学では anode / cathode が必ず対で出るので、セットで比較すると定着しやすい。特に cathodic protection（陰極防食）のような専門表現で見ると、「陰極側の性質・状態」を指す語だとつかめる。catholic など別語とつづりを混同しないこと。
Start from `cathode`, then add `-ic`, which often means `related to`. So `cathodic` simply means `of the cathode side`, just like `anodic` comes from `anode`. The phrase `cathodic protection` is a strong memory hook.

陰極保護は錆を防ぐ。

cathodic の語源・成り立ち Etymology
cathodic は cathode からできた語で、語源はギリシャ語 kata-「下へ」+ hodos「道」の kathodos「下り道」です。anode と対になるだけでなく、method も同じ hodos を含むので、「流れが向かう道」という感覚で陰極性を覚えられます。
Cathodic comes from cathode, which is based on Greek kathodos, meaning "way down" or "downward path," from kata- "down" and hodos "way." In science, the word was chosen for the electrode seen as the path where current goes downward or inward. The root hodos also appears in method, originally meaning a "way" or "path."
