What is the superlative and comparative form of elaborate?

"Elaborate" is already the superlative form! It means "very detailed or complicated" and there isn't a more extreme version of that.

There is no true comparative form of "elaborate". While you could technically say "more elaborate" or "less elaborate", it's not very common usage. Instead, you'd typically use words like:

* More detailed

* More intricate

* More complex

* More involved

* Less simple

* Less basic

For example, instead of saying "This is a more elaborate plan," you might say "This is a more detailed plan."
