Doesn't seem unreasonable to string a few words together to make sentences, once you have a word add another and then you got something.
Not everyone is a natural writer but anyone can say something even if it's just "wow it's really tough to think of something to say".
I used to get word blocks all the time and then to get out of that I'd just start typing the thoughts in my mind, in no time at all I got back on track.
Cheers.
