More formal alternatives:
* Independent clause: This is the most technically accurate term, as a complete sentence is always an independent clause.
* Simple sentence: If the sentence consists of only one independent clause.
* Declarative sentence: If the sentence makes a statement.
* Grammatically correct sentence: Emphasizes the proper structure and elements.
More informal alternatives:
* Full sentence: This is a straightforward alternative.
* Whole sentence: Similar to "full sentence", but with a slightly more informal tone.
* Proper sentence: This implies that the sentence is correctly constructed.
Ultimately, the best alternative depends on your specific context and the tone you want to convey.
