Fading Vowels: Why Does 'Kemaren' Dominate Daily Speech?

The shift from the [i] vowel to [e] in 'kemaren' is caused by phonetic assimilation and the influence of the Betawi and Jakarta Malay dialects. In daily conversation, speakers tend to relax the articulation of the high vowel [i] into the mid vowel [e] for easier pronunciation during fast-paced speech.

The word 'kemarin' is rooted in Classical Malay 'kemarin,' referring to the day before today. Structurally, this word relates to time markers in the Austronesian language family, which often use the [i] vowel in the final syllable to denote temporal proximity.

The use of 'kemaren' is considered more flexible and intimate in casual urban social contexts. Conversely, the formal form 'kemarin' is often perceived as too formal or stiff for casual chats on social media or informal gatherings.
