Am I right in assuming that sydd yn is the exact same thing as sy’n? That’s what I’m assuming, but best to be sure. And if anyone here has done the first and second course, but hasn’t started course 3, I heartily recommend giving the new course 1 a go in between course 3 lessons - I promise you’ll actually learn stuff, and it’ll remind you how far you’ve come when course 3 starts getting harder ;).
Spot on Chris, sy’n is indeed a contraction of sydd yn.
Hwyl,
Stu
