ברכות לה,א

In Tosfas Maseches Rosh Hashonoh (33,1) paskens an unnecessary brocho is only assur miderabonon and therefore women make a brocho on time dependent mitzvos. It is not considered nikro hedyut since the men are mechiyuv. Maybe, women have a kiyum mitzvo so they can say they were commanded. In SA O’CH (215,4) it paskens like the Rambam that it is min hatorah based on לא תשא, swearing falsely or uttering Hashem’s name in vain. So how could chazal institute brochos? They can institute new rules based on לא תסור, not to sway from there words, so once they instituted brochos, it is not in vain anymore. They said that if there is question whether it was said, don’t repeat. If there is a minhag, like tefilin chol hamed, we say the brochos.
The nusach of brochos is interesting. The Chinuch 430, explains that ברוך means that He Is the source of all blessings like a well of all blessings. אתה, you, directly but the rest is in third person. We bless Hashem, like a son who is riding on the shoulders of the father (remember Rashi ויבא עמלק as mentioned before, but we do recognize Him) who provides us with our needs and the ‘how’ is indirect, hidden from us.
