Diklah

Both names have a connection to nature and agriculture. 'Demetrios' is derived from Demeter, the Greek goddess of agriculture and harvest, mirroring Diklah's association with the date palm.

Arjun, a central figure in the Mahabharata, embodies strength, resilience, and a connection to nature, qualities that resonate with the potential symbolism of Diklah.

Both names possess a somewhat uncommon and distinctive sound, evoking a sense of uniqueness and quiet strength.
