What is the difference between "What got into her" or "What has gotten into her"?
What is the difference between "What got into her" and "What has gotten into her" ?
Solution 1:
This is a simple case of differing tenses. Got=past tense while gotten=present progressive.
So if you're trying to say something 'got' into her in the defined past then use that, but if you mean it's an ongoing reaction, use 'gotten.'
