In English an orphan is:
A paragraph-opening line that appears by itself at the bottom of a page or column, thus separated from the rest of the text
Thus, in English typography it is understood in the context of the whole paragraph. Single line of a new paragraph, left alone on the preceding page (before page break) is not allowed.
Polish language is more strict by that and “explores” an alternative (less known) definition of “orphan”. In Polish typography this term is understood in the context of single line and regarded as a:
Single word (single letter in most cases) left along at the end of line (next to right paragraph).
And similarly this is prohibited in Polish typesetting.
