覚え方のコツ Memory Tip
replaces は replace の三人称単数現在形。replace は無音の e で終わるため、-es を付けて replaces とし、語尾は /ɪz/ と発音する。主語が this app、the machine、it など単数なら使える。A replaces B は「AがBに取って代わる」、replace a broken part は「壊れた部品を交換する」。
Replaces comes from replace and is used with a third-person singular subject such as he, she, it, this app, or the machine. Because replace ends in a silent e and an s-like sound, add -s in spelling to make replaces, with the ending pronounced /ɪz/. Remember the pattern “A replaces B”: the new app takes the old app’s place. In another common pattern, someone replaces a broken part, meaning the damaged item is removed and a new one is installed. Both patterns preserve the central image of one thing taking another’s place.
例文

The machine replaces broken parts quickly.
その機械は壊れた部品をすばやく交換します。
A password manager replaces many handwritten notes.

replaces の語源・成り立ち Etymology
古フランス語 replacer が語源。re-（再び）+ place（置く）で「元の場所に別のものを置く」が原義。placeはラテン語 platea（広い通り）に遡る。同根語に displacement（置き換え、転位）やmisplace（置き忘れる）がある。
Replaces is the third-person singular present form of replace. Replace entered English from French replacer and is transparently related to re- plus place. Its earliest central idea was putting something back in a place, after which it developed the sense of putting one thing where another had been. Place came through French from Latin platea, referring to a broad street or open area, ultimately from Greek plateia.
