And to abs

My iPhone ALWAYS 100% of the time will change the word "and" to "abs" This started happening in the past 3 months. I've had an iPhone since the 4 was out and NEVER had this happen. I went in to setting to text replacement and put in shortcuts to write the word and, but it still changes it to abs. I don't think I have ever in my life typed the word abs for any reason. Can you figure out what is going on and fix it. This is pretty annoying.
