What does Delilah mean?
Meaning uncertain. Usually traced to the root dalal, 'to hang low, be low, languish, weaken,' giving the common glosses 'delicate' or '(she who) weakened' — and the Samson narrative plays on her bringing him low (Judges 16). Competing proposals include 'temptress' (from an Arabic root) and a shortened theophoric tied to Ishtar; some lexicons simply mark it 'unknown.' Treat as disputed.
What does Naomi mean?
From Hebrew No'omi, 'my pleasantness, pleasant' (root n-'-m, 'to be pleasant, agreeable'). In Ruth 1:20 Naomi asks instead to be called Mara, 'bitter' — a deliberate biblical contrast that turns on the name's meaning.
