Why Writers Use “So Too” in Formal English
The phrase “so too” does more than mean “also.” It creates a stronger relationship between two ideas.
Compare these examples:
Basic Version:
“Technology changed communication. Social media changed communication too.”
The meaning is clear, but the repetition makes the writing feel plain.
Improved Version:
“Technology changed communication, and so too did social media.”
The second sentence feels more balanced because it connects both ideas.
Writers often use “so too” to create parallel structure.
Parallel structure means presenting similar ideas using similar grammatical patterns.
Example:
“The new rules affected employees, and so too did they affect managers.”
The matching structure makes the sentence smoother and easier to follow.
Alternatives to “So Too”: Other Ways to Express Similar Ideas
Although “so too” is correct grammar, it is not always the best choice. English provides several alternatives that may sound more natural depending on the situation.
“So Too” vs “Also”
The word “also” simply adds another piece of information.
Example:
“Emma studies English. She also studies history.”
This means Emma studies both subjects.
However:
“Emma studies English, and so too does her brother.”
This means her brother studies English in the same way.
The difference is that “also” adds information while “so too” highlights similarity.
“So Too” vs “As Well”
The phrase “as well” is common in everyday English.
Example:
“I enjoy reading as well.”
It sounds relaxed and conversational.
Compare:
“I enjoy reading, and so too does my sister.”
This places more attention on the fact that two people share the same interest.
“So Too” vs “Likewise”
The word “likewise” has a similar meaning.
Examples:
“The first group supported the idea, and likewise did the second group.”
“The first group supported the idea, and so too did the second group.”
Both sentences work.
However, “likewise” often sounds slightly more conversational, while “so too” has a more formal and structured feel.
“So Too” vs “Similarly”
The word “similarly” focuses on comparison.
Example:
“The first study showed positive results. Similarly, the second study showed positive results.”
Meanwhile:
“The first study showed positive results, and so too did the second study.”
The phrase “so too” creates stronger grammatical balance between the two subjects.
