īstens

Apparently from īsts (“true, real”) +‎ -ens. Comapre Russian истина (ístina, “truth”).

• IPA^(key): [īːstɛns]

īstens (definite īstenais, comparative īstenāks, superlative visīstenākais, adverb īsteni)

1. real, true, genuine

   mājas īstenais saimnieks ― the true, real owner of the house

   ģimenes īstenais apgādnieks ― the family's true, real provider

   visās zemēs īstenie dzimtenes patrioti vienmēr bijuši un ir darbaļaudis ― the real patriots in all lands are and have always been the workers

   īstens, patiess un vērtīgs būs tikai tas darbs, kas attēlo dziļāko patiesību ― real, true and valuable is only the work that represents the deepest truth

2. true, correct

   atrast īsteno atbildi ― to find the true answer

3. (of members of a society) full

   akadēmijas īstenais loceklis ― full member of the academy (the highest, most honorable form of membership)

In most cases, īsts and īstens are interchangeable, with īsts being usually the preferred, more modern term. One exception, though, is akadēmijas īstenais loceklis, where īsts is not used.
