Syag Lchochma
an ayin is an eye. show them closed eye and say it makes no sound cause it’s sleeping.
Please don’t teach falsehood to your tots. Ayin is not Oleph:- Period!
Ayin does have a sight nasal sound. After all, where do you think the diminutive of Yankel came from Yaakov? Simple:- Because the Ayin in Yaakov as in in all Ayins, has a slight Gutteral/nasalised sound, so please please teach your students the correct & authentic & only way of pronouncing “Ayin”. Thank you.
