​(A proofreader's note regarding “into” and “in”)

When deciding on “into” or “in” as the appropriate choice in a sentence, a major consideration is whether the moved item (i.e., transported in space or time) becomes enclosed by something else. However, “into” is generally used for transformations of state as well as in a relatively few phrasal verbs. The latter more commonly involve “in” than “into” and simply need to be recognized as such. Furthermore, “to” is not combined with “in" when it occurs as part of an infinitive verb.

Use “into” when moving in space or time
Unless “in order to”;
For transformations, choose as well
Since “into” there is true.

To keep the two apart at times,
Consider phrasal verbs;
Is “in” within the given phrase?
Infinitive “to” in blurbs?

Some phrasal verbs will sport “into,”
And sometimes it will tell
Of special interests closely held,
Like “into styles that sell.”
