Unknown; likely a modern American creation
Shantara is a modern American name with no singular established etymology. It likely emerged as a rhythmic blend of the popular prefix 'Shan-' (as in Shannon or Shandra) and the suffix '-tara', possibly influenced by the Sanskrit name Tara. Because it lacks a historical root, its meaning is often interpreted by parents through its phonetic components.
