köken: an + genehm, from Old High German nami, ultimately from the same root as nehmen. Compare Sanskrit नमस्ते (namaste, “salutations (to you)”) for similar semantic development from the same Proto-Indo-European root.
köken: örülök (“I am glad”) + hogy (“that”) + megismerhetem (“I can get to know [you]”), omitting önt (formal “you”, accusative) as it is implied by the definite conjugation.
