What part of speech is “except”
Preposition
Definition:
Except as a preposition is used to express a qualifying limitation to a rule or statement.
Rules:
In its prepositional form, except is used to introduce something that isn't included in a previous statement, which otherwise could be assumed to be included in the scope of the statement. These could be people, objects, or concepts.
Examples:
1. We invited everyone except for Joe.
2. She read books except for the novels.
3. We played every game except for the card game.
Tips:
It is important to remember that when except is used as a preposition, it only suggests that whatever follows is excluded from a previously stated context. There may be other elements or exceptions to the statement that are not mentioned.
