よう after (negated) short form of verb

Question

In the sentence (found in Kanji in Context's workbook)

事故を起こさないよう、万全の注意を払った。

I assume 起こさないよう is the negative short form of 起こす followed by よう. But I can't find an explanation, or other occurrences, of such a construct. According to google's translation tool, the sentence means something like

I paid perfect attention so as not to cause an accident.

So, よう following the short form of a verb indicates goal/purpose? Is that correct? If so, could you point me to a reference, or to other occurrences?

Answer 1

I always assumed this was the same as ように.

EDIT: as the comments say, よう without the に is more formal.

Answer 2

“よう” indicates purposes, and it’s directly translated as “so as to~”.

In the sentence “事故を起こさないよう“, “起こさない” is the negative form of “起こす“, followed by “ない(means “not”). The following word ”よう” means “so as to”.

So, the sentence as a whole is translated as “so as not to cause an accident”. To say “so as not to do something”, you can say the negative form of any verb followed by “ない“, and put “よう“ at the end.

For example,

1. 風邪をひかないよう、気を付けて下さい。 =So as not to catch a cold, please take care of yourself.

2. 試験で失敗しないよう、たくさん勉強して下さい。 =So as not to fail in the exam, please study a lot.

“よう“ sounds quite polite and formal, so “ように” is more common to be used in conversations ( both words have exactly the same meaning ).

Hope it helps!
