privilege
No D. There is no D anywhere in privilege.

Wrong: priviledge
Right: privilege
No D. The vowels run i-i-e.
The trick
No D, and the vowels go i-i-e. PRIV-I-LEGE.
The phantom D arrives from knowledge and acknowledge, which do have one. The -lege ending here comes from Latin lex, law—the same root as legal, which also has no D.
Now go delete the D.
