I came across many sentences with the phrase 'become a law' as in 'In 1857 the bill passed the legislature and became a law'. But in dictionaries there's only the phrase of 'become law'. Are both phrases good English?
I don't think there's anything grammatically wrong with "become a law", but "become law" is the normal expression.
I'm not a teacher of English, but I have spoken it for (almost) all of my life....
