Archaic: to catch sight of; to spot or perceive something after searching.
From 'be-' (prefix) + 'spy' (to catch sight of). The prefix may intensify the verb or suggest completion of the spying action.
Though archaic, 'bespy' appears in Renaissance literature—'I bespy a ship on the horizon'—and shows how the 'be-' prefix once allowed writers to subtly shift the meaning of common verbs to suit meter and tone.
