פירוש על קידושין 11:8

The Talmud here is asking about all of the unclear betrothal formulae we have seen over the past few sections. What was the context in which he gave the money to her and said these things. If they were talking about getting married, then even if he says nothing and gives her the money, she is married, at least according to R. Yose, whom the halakhah follows.
And if they were not talking about getting married, how is she supposed to know what he is saying. The formulas listed above do not sound completely like betrothal formulas.
