The act of overflowing or exceeding boundaries; an overflow or outburst.
From 'debord' plus the suffix '-ment' (from Old French and Latin, indicating a state, condition, or action). This creates an abstract noun from the verb meaning to overflow.
The '-ment' suffix came to English primarily from French legal and administrative vocabulary, which is why it often appears in formal or official-sounding nouns like 'government,' 'agreement,' and 'debordment.'
