Yes, I tend to speak in sentences - obviously so when I'm speaking to an audience, but also in private life. What tends to go - or tends to be different, perhaps - is the use of grammatical constructions. For speech, I have no qualms about using prepositions to end my sentences with, or all the other things that have been YARTed to death and back in this forum.

My main problem these days - with advancing years - is that I, from time to time, find myself stuck for a word, which can really mess up your sentence construction.

For really snappy complete spoken sentences, you can't beat a good imperative: "Go."
For a short while, I worked as a dog handler and found the imperatives used there were very satisfactory
