Subjek or Subyek? Tracing the Latin Loanword Origins

The use of the variant 'subyek' often occurs due to the influence of the old spelling system (Soewandi Spelling), where the letter 'y' was frequently used for semivowel sounds. Additionally, there is a community tendency to follow a pronunciation that sounds as if it has a 'y' insertion in the middle of the word (pseudo-diphthongization).

This word originates from the Latin term 'subiectus', which was subsequently adopted into English as 'subject' and Dutch as 'subject'. During the standardization process of the Indonesian language, the phoneme 'j' was selected to represent the sound to maintain local phonetic consistency.

The variant 'subyek' is still very commonly found in old academic literature and legal documents inherited from the colonial era. This creates a perception that the form with a 'y' appears more formal or 'intellectual', even though according to modern linguistic rules, that form is non-standard.
