This is a question to the asker. There is a problem with this question, namely the definitions cited suggesting the use of "stanza" as it is used in modern poetry, as a synonym for "verse" or "strophe". In Hungarian poetry analysis, "stanza" refers to a specific type of verse. In English that specific type of stanza is differentiated by names such as "ottava rima", "sicilian octave".
If the question definitely refers to the use of "stanza" as "verse" or "strophe", please make it clear in the English definition above. I suggest replacing the definition with the one in Wikipedia: "In modern poetry, the term is often equivalent with strophe; in popular vocal music, a stanza is typically referred to as a "verse" (as distinct from the refrain, or "chorus").
A stanza consists of a grouping of lines, set off by a space, that usually has a set pattern of meter and rhyme."
