In an essay can you put 'it became aware to me'?

Answer 1

No. "Aware" is for conscious creatures only. Use either "I became aware of it," or something like "It became known to me," or "It became apparent to me.

Answer 2

Yes, you can use the phrase "it became aware to me" in an essay. However, it is more commonly expressed as "I became aware" or "I became aware of." This phrasing is more direct and concise.
