Get it right: maybe
Don’t confuse the adverb maybe (one word), which means ‘perhaps’, with may be (two words), which means ‘could be’:
✗ In an earthquake your house maybe badly damaged.
✓ In an earthquake your house may be badly damaged.
✗ It maybe an unfulfilled dream.
✓ It may be an unfulfilled dream.

Now, maybe I haven’t explained myself very well.
There are, perhaps, three principles which must be followed.
