Commentary for Kiddushin 9:19
אלא פריך הכי ומה כסף שאינו גומר קונה
Let then intercourse prove it.<span class="x" onmousemove="('comment',' Which acquires a woman though lacking this power.');"><sup>38</sup></span> As for intercourse, that is because it acquires in the case of a yebamah! Then let money prove it.<span class="x" onmousemove="('comment',' Which cannot acquire a yebamah, yet effects betrothal.');"><sup>39</sup></span> And thus the argument revolves: the distinguishing feature of one is not that of the other, nor is the distinguishing of this one that the other; the feature common to both is that they acquire elsewhere, and acquire here [in marriage]; so do I adduce huppah, which acquires elsewhere<span class="x" onmousemove="('comment',' After betrothal.');"><sup>40</sup></span> and acquires here too.<span class="x" onmousemove="('comment',' I.e., it can effect the first stage of marriage, sc. betrothal.');"><sup>41</sup></span> [No.]
