My wife and I have been playing a word-of-the-day game on and off for a year or so. Though the pace is slow, it’s probably been one of the most effective ways of picking and retaining new vocabulary I’ve used; especially now that we’ve moved back to the US.
Yesterday’s word came up while watching Karei Naru Ichizoku, a Kimutaku drama about Japanese business and power in post-WWII Japan.
徹底的（tetteiteiki） — exhaustive
Lots of tetteiteki this and that in Karei Naru Ichizoku. Business, politics, power. Lawyers. Lawyers and exhaustive research into the nether regions of business. 徹底的な研究 of some such product, 徹底的な検査 to prepare for the upcoming trial.. yada, yada. As for me, the drama kind of induced me to 徹底的に寝る。
