Thank you very much, Josef!
I have found some examples of "break off" in the dictionaries. Are they Standard English or regionalism?
1. Finally we would break off for coffee and to talk more informally. [pg. 35, Oxford Dictionary of Phrasal Verbs by A.P.Cowie & R. Mackin]
2. Let's break off and have a cup of tea.
2a. Let's break off work and have a cup of tea. [Longman Dictionary of Phrasal verbs by Rosemary Courtney]
