覚え方のコツ Memory Tip
原形 interact に -ing をそのまま付けた現在分詞・動名詞で、強勢は原形と同じ第3音節にあり、語尾は /ɪŋ/ です。inter-「間で」＋ act「働く」と分け、二者が一方通行でなく互いに働きかける像を作ります。interacting with people／an app や chemicals interacting の形で覚えましょう。
Form interacting by adding -ing directly to interact; no final letter is dropped or doubled. The stress remains on the final syllable of the base, and the new ending is pronounced /ɪŋ/. Divide the idea into inter-, “between,” and act, “do or operate”: two sides act between or upon each other. Picture students interacting in English, children interacting with an app, or chemicals interacting inside a bottle. The key is two-way involvement or mutual influence, not a one-directional action. Learn the frequent pattern interact with someone or something, alongside two things interacting with each other.

interacting の語源・成り立ち Etymology
ラテン語 inter-（間で）+ agere（行う・動く）から。「互いの間で作用し合う」が原義。関連語: interaction（相互作用）、agent（行為者）。agere は「動かす」が根本で、二者が互いに働きかけ合う様子を表す。
Interacting is formed from interact plus the present-participle ending -ing. Interact combines inter-, “between or among,” with act, from Latin agere, “to do, drive, or set in motion.” The verb therefore expresses action occurring between participants. It entered modern use for reciprocal social activity and for processes in which physical objects, chemicals, or systems affect one another. Interaction and interactive belong to the same modern word family.
