Teneki (TEN-ne-key): Surely, certainly, definitely, must.
Note: This is also said tieneki and tieneski. It comes from the Spanish phrase "tiene/tienes que..." which means "you have (must) ..." However, Chamorro uses the phrase to indicate something will certainly occur.
"Teneki ma sangåni hao gi despues." = "They'll surely tell you afterwards."
"Ai na inaguaguat na påtgon, tieneki u masaolak." = "What a naughty kid, he's definitely going to be spanked."
"Nangga sa' teneki måtto." = "Wait and it will certainly come."
