Such paraphrasing might bring out the meaning, but it may also be that further analysis is required, even beyond 'natural language'. The force component is perhaps the type of sentence we had originally, or some part of the paraphrase. Different theorists break it up in different ways. Thus Austin said that every utterence has an 'illocutionary force', which is the speech-act actually performed by its production. Kenny is quite unusual in distinguishing between only two types of force.
Sentences are all 'fiats' or 'assertions'.
Which they are is to be discovered by 'matching them up to the world' to see which is right or wrong. They are definitions. They stipulate a mode of analysis. Wittgenstein himself was very keen to say that definitions are rules, and cannot be compared with the world to see whether they are right or wrong, true or false. In 23 of 'Philosophical Investigations' Wittgenstein claims that there are countless different kinds of sentence, and that the number is not fixed.
