What does write for readers mean?

Answer 1

To 'write for readers' is the same as 'consider your readers', which both mean, you must consider the audience who will be reading what you write. If you were writing a young children's simple story book, you would not use large words like bio-degradable or approximate. But those words would be good if you were writing to a high school or college audience, i.e. people with higher education.
