Adjetivos em inglês terminados em Y

Ola pessoal,

Nem sei se este seria o titulo certo ja que nao tenho nem certeza se sao adjetivos, mas acho que sao. Procurei na lista de adjetivos aqui mas nao achei entao gostaria de saber mais sobre aquelas palavras que transformamos em adjetivos colocando o y no final por exemplo, greed, greey[u]. smile, smile[u]y. what are the rules to transform nouns to adjetives, also i'd like to know about informal english, other day i heard my husband describing a banana ice cream and he said "oh that ice cream is very banany" i don't even know if we would write like that and people say other words like that a lot, carroty, and he said they are not real words, is there a rule or list of adjectives is correct to say???

Thanks

Ps: Sorry guys I've just realised I started in portuguese the question and ended it in english lol

Sophia, as your husband said, these aren't "real" words. They are spur-of-the-moment creations, and the basic "rule" (I'm inventing one) as to whether you can just add a -y, is probably (1)whether it sounds right and flows easily off the tongue and (2)there is no loss of meaning.

Some are so convenient as to have become legitimate, and I can think of many ending in d, or t: seed - seedy, greed - greedy, bead - beady, meat - meaty, salt - salty, sweat - sweaty, etc. Others just don't work, presumably because the meaning would be unclear: feed - feedy, feat - featy, bald - baldy.

Are these "legitimate" words? lemony, sugary, peppery, yeasty, softy (hardy is). I don't even know, but if you hear them you know what they mean.

This is kind of a loosey-goosey explanation, I know.

Complemento,

O sufixo (-y) é usado para se formar adjetivos a partir de substantivos.

Sugary desserts (=full of sugar)
Dirty hands (=covered with dirt)
A messy room (= a room that is a mess)

Mais importante do que saber a regra, é conhecer na prática; muitas vezes, você vai formar um adjetivo com "y" mas não vai conhecer a praticidade deste, sendo que, pode ser que venha a não existir.
Thanks guys, it's good to know I didn't miss anything, I was just worried I had missed this class when I was studying english and because of that I didn't know the explanation, but I guess it's a little bit of a grey area to everybody...
