extern
adjective
1. (obsolete, rare) External; outward; not inherent.
- "Heaven is my judge, not I for love and duty,/ But seeming so, for my particular end,/For when my outward action doth demonstrate/The native act and figure of my heart/In complement extern, 'tis not long after/But I will wear my heart upon my sleeve/For daws to peck at." (Othello, Act 1, Scene 1)
