tentu
The archaic spelling form (Van Ophuijsen) 'tentoe' commonly used during the Dutch East Indies colonial era.
pastinja
'Pastinja' is the archaic spelling of 'pastinya', used in old-era texts to reinforce statements of certainty, similar in function to 'tentoe' within the same historical context.
The word tentoe is the Van Ophuijsen spelling of tentu, the official orthographic system used during the Dutch colonial era, later replaced by the Republican Spelling (1947) and the Perfected Spelling system (1972). Under Van Ophuijsen conventions, the vowel sound /u/ was consistently rendered as “oe”, following Dutch phonetic tradition. The root word tentu originates from Classical Malay and appears frequently in colonial-era Malay-language newspapers such as Bintang Timoer and Pewarta Deli. Its usage reflects the elevated Malay register employed by the educated class and aristocracy in the early 20th century.
Soedah tentoe jang kita, orang toeanja, soeka terima kabar baik dari anaknja. (Sudah tentu kita, orang tuanya, suka menerima kabar baik dari anaknya.)
