cathodic
陰極の
解説 Definition
陰極に関する、または陰極で起こる性質を表します。陰極は電気化学で還元が起こる電極を指し、装置や反応の種類によって正極になることも負極になることもあります。
Cathodic means relating to the cathode, which is an electrode in an electrical or chemical system. It is often used in chemistry, electronics, and engineering, for example in batteries or corrosion protection.
覚え方のコツ Memory Tip
cathode(陰極)の形容詞版が cathodic です。anode に対する anodic と同じ型で、「陰極側の・陰極に関する」と覚えます。cathodic protection(陰極防食)や cathodic reaction(陰極反応)のように、電極の働きや反応位置を示す語として見ると定着しやすいです。
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.
例文
The cathodic protection prevents rust.
陰極保護は錆を防ぐ。
Cathodic reactions occur at the cathode.

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."
