Expert writing Tips

Best practice

When writing in a highly technical or academic context, consider if a more descriptive adjective like "effective", "efficient" or "accurate" provides better clarity than the general nature of "so good".

Common error

A common mistake is using "so good" to describe an action rather than a state. In formal writing, use "<a href="/s/so+well" target="_blank" rel="alternative">so well" when modifying a verb. For instance, say "The system functioned <a href="/s/so+well" target="_blank" rel="alternative">so well" instead of "functioned so good".

Linguistic Context

The phrase "so good" functions as an adjective phrase where the adverb "so" acts as an intensifier for the head adjective "good". Based on Ludwig examples, it is frequently used to provide subjective evaluation or to emphasize the high quality of a subject.
