I could not find this answered specifically, so I apologize in advance if this is a duplicate.

If you make a pronunciation mistake, or lose your place in the final section of the amidah, can you go back the the start of a sentence you have not completed? For example, say I lose my place in יהי רצון מלפניך, can I simply restart the sentence from יהי?

I assume you can, since one who says שלם אב on a fast day and realizes before they complete the blessing is instructed to simply restart at שים שלום, but wanted to confirm.

If so, can you always restart a section that you have not yet completed?
