Hello
@AngelinaBallerina and welcome from me too.
My wife has this aspect to her dementia. My wife was a true wordsmith(winning prizes for the Times crossword and the like) so it is so sad watching her slowly lose her language skills. We are now 4-5 years since diagnosis and at times I have to tell my wife that I just don't know what she is trying to say( as it just comes out as gibberish). Most of the time we make something of a game of it as I can often guess what she's trying to say.
One aspect that has become more troublesome is the loss of understanding in relation to what I'm saying. An example would be if I ask my wife to get the milk from the fridge and she may not understand either 'milk' or 'fridge' so I have to point at whatever I'm talking about - which can be awkward if I'm busy with something. I also have to talk very slowly and deliberately otherwise my wife can't follow what is being said.
If you have any question just ask and I'll see if my experience has given me an answer.
