覚え方のコツ Memory Tip
poly はギリシャ語 polys「多い」に由来し、polygon「多くの角をもつ図形」、polyglot「多くの言語を使う人」のように「多数」を示します。一方、英語圏では文脈により polytechnic「総合技術学校」のくだけた略称にもなります。単独の名詞か、語頭要素 poly- かを周囲の語から判断しましょう。
Use one central idea: Greek poly- means “many.” In polygon, it points to many angles, and in polyglot, to many languages. Seeing several familiar examples makes the combining form easy to recognize in new vocabulary. Poly can also stand alone informally as a shortened form of polytechnic, especially when people refer to a technical college or institution. Check the context: attached to another element, poly- usually contributes the meaning “many”; used as a noun in a school-related sentence, poly is likely the abbreviation for polytechnic.

The combining form poly- comes from Greek polys, meaning “much” or “many.” It entered numerous learned compounds, including polygon and polyglot, and remains productive in scientific and technical vocabulary.

Polytechnic itself combines Greek-derived elements expressing “many” and “arts or skills,” reflecting an institution that teaches multiple technical or applied subjects.
