Hi Tuar ceatha,
úrscéal = OORSH-KYALE (or in my northern dialect OOWIR-SHKYEYL)
Not sure about courses in Cork. University College Cork is one of the most renowned centers of Irish learning in the country they would have evening courses, summer courses and night classes. I would imagine they have workshops over a few days for beginners. However Cork city is predominantly English speaking so you wouldn't get the 24/7 exposure to the Irish language you would get in a 'Gaeltacht' (Irish speaking) area. In West Cork places such as 'Muskerry' 'Coolea' and 'Ballingeary' are gaeltacht areas and may also do local workshops.
Kerry would be another close 'gaeltacht' its about an hour outside Cork, An Daingean (or Dingle) is the name of that gaeltacht. Dingle, Ventry and Ballyferriter etc. are all scenically beautiful also.
UCC would be the first venue I'd check out though to get your feet wet.
The dialect you wish to learn is called 'Gaeilge na Mumhan' [GUALE-IGA NA MOO-WIN] (Munster Irish, Munster being the southern province of Ireland.
)Irish grammar and english grammar are so very unsimilar that oftentimes Google translate gets confused because phrases don't exist in Irish as they do in English. So just to be wary of that.
Adh mór (Best of luck)
