click

パソコン、それもウィンドウズの全盛になってからは“クリック”は最早常識となりましたが、英単語のClickには、擬音語としての意味があります。


カチッ,カチリ,カチカチ,カチャッ


英和辞典のエントリでは上記のような訳語が見られると思います。American Heritage Dictionaryによりますとこれは、


A brief, sharp, nonresonant sound


と定義されており、実例として、


the click of a door latch


とあります。ドアが閉まるときの、“カチャッ”という音を指しているのでしょう。

ところで、動詞としての意味には、“（カチッ,カチリ,カチカチ,カチャッ）といった音をたてる、音がする”という意味から発展して、


ピンとくる、合点がいく (AHD: To become clear; fall into place)


という意味があります。例えば、下記の引用例では、アイデアがひらめくタイミングについて、"click"を充てています。日本語にしてみれば、アイデアが“ポンポンと”浮かぶ、といったところでしょうか？


"If you can't come up with new ideas, you don't belong here, " says senior Paul Kirley, who in five years has designed bathroom scales, lamps, helmets, and toilets. " They can't teach creativity, but they can help you harness it and shape your ideas on a professional level." Some ideas click right away, he says, " like the guy who said it would be cool to have a motorcycle in water and invented Jet skis. "
(Student Creators Tackle Poor Design. Christian Science Monitor. 1991.)


その他の意味として、ウマが合う、（特に異性と）フィーリングが合う、意気投合する、という意味もあります。下記もその意味での引用です。


Gruden knew that Gannon, being wooed by other teams, had concerns about the Raiders. So he played to Gannon's no-nonsense style. "We went to dinner at some Mexican joint, and, on the way, back, we stopped at a 7-Eleven, and he bought a six-pack of beer, and we came back to the facility and sat in his office for three hours and watched film," Gannon says. "I knew right then." "I felt we clicked right away," Gruden says. "I had never been around a guy that passionate about playing. " The two were in Gruden's office until 1 a.m. Gruden showed Gannon tapes of Raiders games and practices to prove the team was headed in the right direction. But Gannon, who turns 35 next week, was in search of much more.
