Names in Irish to describe a person (characteristics etc.)

The huge selection of words for describing people and their character in Irish is one of the aspects in which the language is very rich. I've found that using an electronic dictionary like WinGléacht has made it much easier to find the appropriate ones (Type in 'person' and see the huge number of examples that will come up). I think it'd be worth a thread for people to post the ones they know. Feel free to check a reference and enlighten the rest of us.

Here's the first one:

Drochairteagal - bad article, a bad and dangerous person.*


*Foclóir Uí Dhónaill (WinGléacht)
