Yeeeah maaaybe still I would think that at least in my language is easier in english seems to be more crazy maybe I'm biased IDK.

See gendering in spanish has a general rule with few exceptions
Ends with -N, -O, -R, -S, -L, -U -I 99% chance of Male gendering
Ends with A, -DAD, -TAD, -ED, -SION, -CIÓN, -DEZ, -TIS, -IZ 95% female gendering. Some words that end with -MA, -PA and -TA can be male many exceptions there watch out. Now you would be asking there should be many more endings to words... And I'd say male gender for everything unless the subject is established to be female. Now yes there are tricky ones that change the meaning with the gender
El cura - the priest
La cura - the cure
El papá - the dad (note it also has a tilde)
La papa - the potato
I believe anyway the ambiguos ones are not many really if they are more than a hundred I'd be surprised more than 2 hundred nearly impossible but I'm no linguist.

Now I think this would be a summed up version of the rule but I'd say is pretty close to the thing and fits a paragraph, personally for what I've seen I think the hard thing is getting used to handle gendering without thinking in gender. That's confusing for many English speakers and some Japanese complaint bout the same.
