I don't know if this is exactly what you are referring to . But, I will guess and let me know if I was correct.
Here are some examples.
"to be more understanding".
"I disagreed with her viewpoints, but I listened carefully because I've been trying to be more understanding".
"to be more + verb" as in "to be more caring".
To be more caring I made my girlfriend breakfast this morning.
So generally, use the gerund. The gerund is just take the verb... like "to understand" and add "ing" and remove the "to" to make it a noun. Becomes "understanding".
