First of all, i can't understand how you could have a down-vote on a question. People are odd, so I'm giving you a lingot to make up for it. Secondly, I'm not sure if this helps but the sound at the end here is her tongue touching her teeth, almost like she's saying "fo-vird". It's similar to the Scandinavian rolled R but not as strong. It's also a dialectic thing because where I'm from (north east) the r at the end would be clearer so it'd sound like "fo-vur"
Below a link to a decent summary site, without explanation:
I tried to make senseout of GnG, but could not. Probably this is one of the issues, which have always been and are better left without asking "Why?"
Fómhar means "harvest" or "autumn". In the Irish calendar, Spring starts on the 1st of February, Summer starts on the 1st of May (Bealtaine), Autumn starts on the 1st of August (Lúnasa), and Winter starts on the 1st of November (Samhain). The months of Bealtaine, Lúnasa and Samhain take their names from the feast days that are celebrated at the start of those months.
Méan Fómhair is "middle of autumn" (September) and Deireadh Fómhair is "end of autumn" (October).
