I am associated with holidays.
Change one letter and I am a coating.
Add one letter and I am acceptance of truth.
Change one letter and I am an edge.
Change one final letter and I am a tuft of feathers.
What was I and what did I become?
I am a favourite drink. Add one letter and I am a blue-green colour. Change one letter and I am a business agreement. Change another letter and I am a small valley. Change one final letter and I am a percussion instrument. What was I and what did I become?
I am an alloy.
Change one letter and I am pastureland.
Change another letter and I am a hard, transparent substance.
Change a further letter and I am a group of pupils.
Change one final letter and I am a confrontation.
I am a true statement.
Change one letter and I am an agreement.
Change another letter and I am history.
Change a further letter and I am successful.
Change one final letter and I am a religious ceremony.
