A Vergence, You Say...

Qui-Gon Jinn: 

I have encountered a vergence in the Force.

Yoda: 

A vergence, you say...

Mace Windu: 

Located around a person?

Qui-Gon Jinn: 

A boy. His cells have the highest concentration of midichlorians 

I have seen in a life-form. 

It is possible he was conceived by the midichlorians.

Mace Windu: 

You refer to the prophecy of The One Who Will Bring Balance to The Force. 

You believe it's this -  boy?

verge (n.)

"edge, rim," mid-15c., from Old French verge "twig, branch; measuring rod; penis; rod or wand of office" (12c.), hence, from the last sense, "scope, territory dominated" (as in estre suz la verge de "be under the authority of"), from Latin virga "shoot, rod, stick, slender green branch," of unknown origin.

Earliest attested sense in English is now-obsolete meaning "male member, penis" (c. 1400). Modern sense is from the notion of within the verge (c. 1500, also as Anglo-French dedeinz la verge), i.e. "subject to the Lord High Steward's authority" (as symbolized by the rod of office), originally a 12-mile radius round the king's court. Sense shifted to "the outermost edge of an expanse or area." Meaning "point at which something happens" (as in on the verge of) is first attested c. 1600. "A very curious sense development." [Weekley]

verge (v.1)

"tend, incline," c. 1600, from Latin vergere "to bend, turn, tend toward, incline," from PIE *werg- "to turn," from root *wer- (2) "to turn, bend." Influenced by verge (v.2) "provide with a border" (c. 1600); "be adjacent to" (1787), from verge (n.). Related: Verged; verging.
