Visage is a literary term for referring to someone's face or facial features. You may notice that some face creams use the word visage to try to sound fancier than they are.
A famous use of visage is in Shakespeare's Julius Caesar. Brutus says: "O conspiracy/Shamest thou to show thy dangerous brow by night,/When evils are most free? O, then by day/Where wilt thou find a cavern dark enough/To mask thy monstrous visage?" Now there's a quote that will help you remember the meaning of visage, and even give you nightmares.

A corps ( "core"; the plural is spelled the same as singular but pronounced /ˈkɔərz/ "cores"; from French, from the Latin corpus "body") is either a large formation, or an administrative grouping of troops within an armed force with a common function such as Artillery or Signals representing an arm of service. Corps may also refer to a branch of service such as the United States Marine Corps, the Corps of Royal Marines, the Honourable Corps of Gentlemen at Arms, or the Corps of Commissionaires.
The military term was subsequently adopted for public service organizations with a paramilitary command structure, volunteer public service organizations, such as the Peace Corps, various ambulance corps, some NGOs, and other civic volunteer organizations. Due to this use of the term, it has also spread to some other civic or volunteer organizations that lack the paramilitary structure.
