Fi (High Galactic)

"You all right, pera?"
"Yes, my fi."

―Han Solo and Pera^[1]

"Fi" was a High Galactic expression used by clergymen following the Sacred Way as a term of address directed at non-clergymen. It meant "male child" and was used specifically with male sentients. Grand Admiral Peccati Syn later named his Star Destroyer after the word.
