All of us desire to do that one day, don't we? Credit to +Ekin Gören !

Golodlam ah in•Eglain geliad ídhranc panui!

[Tongues of the Noldor and the Forsaken we desire to learn perfectly!]

golodlam 'Noldo-tongue' < golodh + lam (dh stops to d before l, gl, cf. Galadlóriel)
gelia- 'to learn' < ñgol-yā (due to Thorsten Renk)
panui 'perfectly, totally, completely' < pan + ui
