kore is used for objects that are close to you
also sore is used for objects that are close to the person you are talking to

so, kinda like:
Kore = This
Sore = That
= Those

this one i had to google
those: sorera
these: korera

the suffix "ra" in japanese gives the meaning of "much" or "very" if I'm not mistaken. It's like a quantifier plus qualifier

though I wouldn't believe me^ this is mostly speculation

some stuff I didn't know some time ago but is kinda useful

e.g. : we use this as "for example" among sentences but I never knew the origins of this term. It means "exempli gratia", in latin, and is actually translated to "for example"

et cetera (etc.): another latin word. Translating literally, "et" means "and" and "cetera" means "other similar things" or simply "the rest". As it has an "and" with it (et) there isn't actual need to write ", etc." or "and etc.", and you don't have necessarily to begin the next word with a capital letter

weeb stuff

oni/onii: older brother, although "oni" means demon or ogre too
ane: brother
ototo: younger brother
onee: older sister
imouto: younger sister
ani: sister

ane and ani have some variations. The most common and the only I know is aneki and aniki which is informal

how do you say "booty" in your country?

here, in portuguese, in "bum bum"

it has alot of synonimes but i'll go with the most common one "terma"

It is "pantat" in Indonesian

we can get in a terma and get all of our pantats off and show our bum bums to each other shall we?

I do regret

Whenever i hear bum bum, i just can't help to think that as a baby talk for booty
