強化
解説 Definition
strengthening は strengthen（強化する）の現在分詞・動名詞で、「強化すること」「強化している」という意味です。能力、関係、制度、体などをより強くする動きや過程を表します。
Strengthening is the act or process of making a person, relationship, system, rule, or physical part stronger. As the present participle of strengthen, it can also describe an action that is currently increasing strength or effectiveness.
覚え方のコツ Memory Tip
原形 strengthen（強化する）に -ing を付けた形で、語末の e は落とさずそのまま strengthening となり、発音は「ストレングスニング」に近い形です。規則・関係・筋肉を以前より強くする進行中の動き、またはその強化過程を思い浮かべ、strengthening rules や strengthening muscles のまとまりで覚えましょう。
Connect strengthening directly with the base verb strengthen, meaning “make stronger.” The ending -ing marks either an action in progress, as in “The city is strengthening its rules,” or the process itself, as in “the strengthening of local services.” Unlike verbs that drop a final silent e before -ing, strengthen keeps its full spelling because it ends in n. Remember it through common combinations such as strengthening muscles, strengthening relationships, and strengthening safety rules: in each case, something is being made more effective, secure, or powerful.
例文

地域サービスを強化することは、多くの家庭の助けになります。

strengthening の語源・成り立ち Etymology
古英語 strengþu（強さ）に動詞化接尾辞 -en を付けた strengthen の現在分詞形。語根はゲルマン祖語 *strangaz（強い）。同根語に strong（強い）、strength（力）がある。「強い状態にする」が原義。
Strengthening is the -ing form of strengthen. The verb was formed from the noun strength by adding the verb-forming suffix -en, literally giving the sense “to make strong.” Strength comes from Old English strengþu, a noun related to strong and ultimately belonging to a Germanic word family associated with firmness and force. The -ing ending creates the present participle or a verbal noun denoting the process of making something stronger.
