Selly

Selly is often considered a diminutive or pet form of names like Sally or Selina. Sally itself is a diminutive of Sarah, a Hebrew name meaning 'princess.' However, 'Selly' also has roots in Old English, where 'sælig' meant 'blessed' or 'happy,' giving it a distinct etymological path. This dual origin contributes to its somewhat ambiguous but pleasant feel.

Over time, as English names evolved, the 'sel-' element found in words like 'silly' (which originally meant 'blessed' or 'innocent' before its meaning shifted) and 'seldom' (meaning 'rarely,' from 'seld' or 'seldan' meaning 'rare' or 'blessed') reflects this older Germanic root. Therefore, while often used as a nickname for Sarah or Selina, Selly can also stand on its own with a meaning derived from Old English.
