Shoshanah, both 'Fluent Forever' and 'Crazy Herb's Hebrew words' (The books) have advice on this.
From FF (the book, here is a bit about the concept of memorizing vocab @ https://blog.fluent-forever.com/how-to-remember-words/ (paraphrasing): assign a mental image for masculine and feminine words. ( I use a blue tie and a pink bow).
So for example, yayin / יין, you could imagine bottles of wine wearing blue ties.
From Herb, http://www.crazyherbshebrewwords.com/ , he goes a step further and suggests you imagine a scene for words that appear to be the opposite gender. For the masculine words, it could be a guy with pink bows in his hair drinking a bottle of wine. (It's really up to you, for feminine words he suggested a woman in a tux - if I remember correctly).
I did the same, I think it's because it's not a copula. Is/are is implied, like I know, ani Yodea. You don't add "is" the wines "are" tasty . But if you are saying dogs are pets , you'd need a copula because you're saying this thing is/isn't that. (I'm learning too so I might be wrong, not about dogs as pets needing a copula just everything else)
Modern Hebrew Grammar book has it as particles of being:
Copied and pasted, it doesn't do Hebrew pasting.... That's why there are those weird characters
simplest sentences: ‘Me Tarzan, you Jane’ a The pattern ¬¢¢ «¦±Õ¢ ‘Yoram is tired’ For sentences of the type ‘Yoram is tired, the falafel is cold’, i.e. noun + ‘be’ + adjective, Hebrew commonly omits the verb: ± °¥ ¥ The falafel [is] cold ¦¢ ± °¥ ¦¢ ¥ ¥ These falafels [are] cold Alternatively – especially after a longish subject like ¥ ¦¢ ¥ ¥ ¥ç ‘all these falafels’ – Hebrew often inserts the ‘particles of being’ ,¢ ,â ¨ ,¦ . Which one is chosen depends on whether the subject is masculine or feminine, singular or plural: Masc. sing. ¬¢¢ « â â© ¥ Ú¦±Õ¢ Our Yoram is tired Masc. pl. ¦¢ ± °¦¥ ¦¢ ¥ ¥ These falafels are cold
