Difference between màth and deag?
What is the difference between math and deag when referring to " good " ?
Deagh only goes before a noun, and lenites it if possible.
There is something slightly different about them, but I can't think how to explain it. Some words are conventionally more likely to take "deagh" than "math" though (e.g. "Deagh bheachd!"). You'd also have to use "math" in a predicative sense, e.g.
- Tha am balach math
Tha am balach droch(ungrammatical)
