Shouldn't you use 'példákat' instead of 'példát' here if you want the sentence "You do not see enough examples."?
no. in hungarian you only use the plural form of the noun, if you don't say anything about the quantity. as soon as there's a word in there that indicates it's more than one, you use the singular form of the noun. e.g: i want apples - almákat akarok. i want three apples - három almát akarok. i want a lot of apples - sok almát akarok.
Eléggé. Also, note that elég comes before the adjective, ie good enough = elég jó. Also also, you can't use elég in the same way as I did in the beginning of this comment. Just saying a plain "elég" means the same as "(it's) enough" in English.
