Agog:

Agog: The word probably derives from the Middle French phrase en gogues, but the semantic link between en gogues (meaning "in a state of mirth") and the earliest English uses of agog, which exist in the phrase "to set agog" ("to excite, stimulate, make eager"), are not entirely clear. The -gog part of the word might make one wonder if agog has a connection to the verb goggle, meaning "to stare with wide or protuberant eyes," as in the manner of one who is intensely excited about something. That word actually has a different origin: the Middle English gogelen, meaning "to squint." In many instances, agog is followed by a preposition, such as over or about.
