Christin,
When writing the seanfhocal an lae posts I tried really hard to group them, but it proved nightmarish, so I'm afraid I gave up. I found that I started with broad categorisation like Love, Money, Health, but that these soon disintegrated, and often depended on interpretation too. Be great if you could share some of your research findings with us here on the site in due course.
Ádh mór ort,
Michelle
