I'm confused about the following examples that Cambridge Dictionary gives:
Formulating new strategies is essential for preparing the corporation to meet and sustain future needs.
uses the pattern something is essential for something, and
Knowledge, skills, and creativity are essential to creating high-value products.
uses the pattern something is essential to do something.
I guess both "to" and "for" above function as prepositions. Does that mean it's still grammatical and natural when I use those interchangeably?
Formulating new strategies is essential to preparing the corporation to meet and sustain future needs.
Knowledge, skills, and creativity are essential for creating high-value products.
I'm aware those are different from
It is essential to research and protect your patent.
which is similar to the pattern it is important to know …
However, I can't tell the reason under the hood. Could someone give me a hint?
