Text messaging suggestions gone

I have a new iPhone six and until this morning I had the new text messaging Suggestions. I would start to type a text and it would give me the choice of three words right above the keyboard that I could select. I really liked that because it invariably selected the correct words I was going to use. I have no idea what happened but I woke up this morning and went to send a text message and all three of those suggestion words are gone. Instead it's working the old fashion way were a little word pops up with a little accident and that so small it's difficult for me to see.

I don't think I did anything but it changed somehow to the old form of text messaging. how do I change it to the new text messaging suggestions where I get a choice of three words?

thanks for any help I hate the old-fashioned way of texting!
