What are some alternatives to "is not only"?

Alternatives include "is also", "is not just", and "is more than", which provide similar meanings with slight variations in emphasis.

Is it grammatically correct to use "is not only" without "but also"?

While understandable, omitting "but also" after "is not only" creates an incomplete correlative conjunction, making the sentence grammatically weaker. It's better to include both for clarity and style.

"Is not only" implies that something has at least two qualities or purposes, while "is just" suggests a limitation to a single aspect or characteristic. The former expands, the latter restricts.
