Answer:
The group of words is a phrase and is missing a verb; it cannot stand alone as a sentence.
Explanation:
"Planning on getting married for over a year" is not a sentence.<u> It doesn't have a subject </u>and is missing a "helping verb." It is a phrase because it doesn't have a complete thought.
It is the helping verb that helps the main verb "planning" in order to describe whether the action is happening in the<em> past, present or future.</em>
Examples of helping verbs:<em> is, are, was, were, been, have, had, has</em>.
To make the example into a sentence, you may say:
"She's been planning on getting married for over a year."
