To flow or stream over; to cover with streaming movement.
From the prefix 'be-' plus 'stream' (moving flow of liquid, from Old English 'strēam'). The 'be-' prefix suggests covering or surrounding with streams.
'Bestream' is so rare that most modern dictionaries don't even include it, yet it perfectly demonstrates how the 'be-' prefix could theoretically combine with almost any noun or verb—language is creative, even when creativity produces words nobody actually uses.
