覚え方のコツ Memory Tip
knew は know「知っている」の不規則な過去形で、-ed は付きません。know /noʊ/ に対して knew は /nuː/ と発音し、new と同音です。現在なら I know his name、過去なら I knew his name と、時間を変えた一組の文で覚えると確実です。
Treat knew as the irregular past form of know, not as a word made by adding -ed. Know is pronounced /noʊ/, but knew is pronounced /nuː/, exactly like new, so both the spelling and vowel sound change. Build a simple time contrast: “I know the answer now” versus “I knew the answer yesterday.” The second sentence places the state of knowledge in the past. Common objects include a name, an answer, a person, or a place. Remember that knew is only the past tense; the past participle is known.
例文

They knew the place.
彼らはその場所を知っていました。

knew の語源・成り立ち Etymology
古英語cnāwan（知る、認識する）の過去形。印欧祖語*ǵneh₃-（知る）に遡り、ラテン語cognoscere、ギリシャ語gnōsis（知識）と同根。関連語：know, knowledge, cognition。語頭のkは古英語では発音されていたが、近代英語で黙字化した。
Knew is the inherited past-tense form of know. Know comes from Old English cnāwan, “to know or recognize,” and belongs to a family ultimately connected with the idea of knowing. Related forms occur in knowledge, cognition, and Greek gnosis. The initial k was once pronounced, but later became silent. The modern vowel of knew differs from that of know because of historical sound changes.
