ברכות של ראש השנה ויום הכיפורים מעכבות זו את זו שאם אינו יודע כולם לא יאמר מה שיודע מהם אלא לא יאמר כלום:

1. If the blessings and shofar blasts are a requirement for each other. And in it is 2 paragraphs. The blessings (in the Shemoneh Esrei) of Rosh HaShana and Yom Kippur are required for each other. So that if one does not know all, he should not say what he knows; rather, he should not say anything

2. Similarly, the shofar blasts (tekiyos) are required for each other. When are these words (true), when he does not know part of the mnemonic sign (i.e. the whole TSR"T), he should not do the part he knows. But the TSR"T, TS"T, and TR"T are not prerequisites for each other, if one knows one or two of them, he should do. Note (Rema): But the Blessings are not prerequisites for the Tekiyos, nor the Tekiyos prerequisites of the Blessings. Whichever he knows, he should do [Tur], so to the order is not a requirement [Ran end of tractate Rosh HaShana]; therefore, if one prays before that he blows, he has fulfilled (his obligation).
