cailín:      coll-een
beog   : should probably be "beag" i.e. small, little. Pronounced roughly "bee-ug" without over-lengthnening the first sound!

chrúite ; croo-it-eh or, in some dialects, crit-eh
na : as is
mbó : m-boh (long)

I'm more used to seeing "deas" (nice, pleasant) than "beag" in this context.
