Diminutive of Natalie or Talia, meaning 'birthday of the Lord' or 'dew from heaven.'
Tallie is a breezy, sunlit diminutive that can spring from several distinguished roots. It most naturally connects to Talia, a Hebrew name meaning "dew of heaven" or "gentle rain," evoking refreshment and blessing. It also shares kinship with Thalia, the Greek Muse of comedy and pastoral poetry, one of the nine daughters of Zeus and Mnemosyne, whose name meant "to flourish" or "to bloom."
Both ancestries give Tallie an aura of creative joy and natural vitality. In modern usage, Tallie has also operated as a nickname for Natalie (from the Latin "natalis," meaning "born on Christmas Day") and even Tallulah, the spirited Choctaw-derived name famously associated with actress Tallulah Bankhead, whose outsized personality made it a byword for theatrical glamour in the mid-20th century. This layered lineage means Tallie sits at an intersection of Hebrew, Greek, Latin, and Indigenous American naming traditions.
As a standalone name, Tallie has a lightness and accessibility that feels at home in any era — it appeared with quiet regularity in the late 19th and early 20th centuries and is now experiencing a gentle revival among parents who want something warm and informal without being invented. It has the gift of feeling both vintage and fresh, like a name discovered in a grandmother's address book and immediately recognized as perfect.
