No, I think I’ve got a good handle on that. Studying German and learning Akkusativ vs Dativ really helped.

I think the challenge here involves a few things:

• It’s hard to remember irregular verbs unless they’re super common.
• The vowel shifts on the right side: present-tense Lie and Lying vs past Lay and Lain.
• Some of the forms on the right are very similar sounding to ones on the left, plus Lay is confusingly used in two rather different situations.
