haphazard

Alexander Bennett氏翻訳の五輪書 "The Book of Five Rings and Other Works" を読んでいます。今日もThe Fire Scroll(火の巻)から引用します。

In the case of individual combat, if your opponent assumes a rear or side posture to conceal his intentions, his mind will be revealed through the movement on his sword if you lure him with a feint. Thus, with object divulged you can snatch victory by utilizing the right approach. You will miss the right rhythm if you are haphazard. Study this thoroughly.

"haphazard" は初めて見る単語ではないようですが、意味を思い出せないので、辞書を見ます。

・Oxford English Dictionary: with no particular order or plan; not organized well: The books had been piled on the shelves in a haphazard fashion.
・Collins Dictionary: If you describe something as haphazard, you are critical of it because it is not at all organized or is not arranged according to a plan.: The investigation does seem haphazard.
・Vocabulary.com: Anything haphazard is random, disorganized, slipshod, or hit-or-miss. A tent erected haphazardly might look more like a big nylon bag of dirty laundry than a place to sleep.
Ever heard the expression "I'll hazard a guess?" In it, the word hazard means "chance," as in "take a chance." Think of the hap in haphazard as short for "happen." Combine hap- and -hazard and you get something that happens (or appears to have happened) by chance. If you approach a math problem with haphazard reasoning, you're likely to get it wrong.
