Passage: Following traditional practice from South India, the father's name is sometimes abbreviated to an initial and placed before the personal name. Thus, a man called Anbuselvan whose father is called Ramanan may be called Anbuselvan anak lelaki Ramanan (formal), Anbuselvan a/l Ramanan (as on his government identification card), Anbuselvan Ramanan or R. Anbuselvan. Whereas, his daughter Mathuram would be called Mathuram anak perempuan Anbuselvan (formal), Mathuram a/p Anbuselvan (as on her government identification card), Mathuram Anbuselvan or A. Mathuram. Although not recorded officially, an Indian woman may use her husband's personal name instead of her father's name after marriage.
