Classical namakarana as described in the Grihya Sutra literature did not necessarily produce only the single name a child would be known by afterward; older custom in many communities distinguished between a formal, often astrologically derived name used for ritual and official purposes and a separate, more private name used within the household, and some traditions describe a further, deliberately obscure or unflattering secret name known only to the immediate family, given specifically to protect the child by making it a less identifiable or less attractive target for malevolent spirits believed to prey on the recently named and therefore newly vulnerable. This layered approach to naming reflects a broader anxiety, attested across many premodern cultures rather than uniquely Hindu, that formally and publicly fixing a name creates a point of vulnerability for supernatural attack, an anxiety namakarana's eleventh or twelfth day timing itself partly answers by delaying the formal, public naming past the first, most fragile days of an infant's life.
Most of this layered, protective naming practice has faded from ordinary contemporary observance, where a single name chosen with reference to astrology, family tradition, or simple preference is typically given once at the ceremony and used from then on, but the older logic survives in some communities' continued habit of using an affectionate household nickname alongside a separate, more formal given name recorded for official purposes.
