In Japanese, kanojo 彼女 means "she," "her," a female third person pronoun, or "girlfriend."
It's the female counterpart of kare 彼, "he," "him," "boyfriend."
In Japanese, kare 彼 means either "he," "him," a male third person pronoun, or "boyfriend," kareshi 彼氏.
It's the male counterpart of kanojo 彼女, "she," "her," "girlfriend."
The "third person pronouns" in Japanese, san'ninshou daimeishi 三人称代名詞, are a bit complicated.
The words kare 彼 and kanojo 彼女 mean "he" and "she," respectively, but they also mean "boyfriend" and "girlfriend," respectively.
There's no "it" pronoun in Japanese.
Often, someone is referred to in third person neutrally, by the noun phrase "that person," ano hito あの人, ano ko あの子, or aitsu あいつ. Sometimes, by yatsu やつ, which refers to an individual person or thing.
Japanese is a pronoun dropping language, which means there are sentences you'd use "he" or "she" in English that you wouldn't use a pronoun in Japanese.
In Japanese, koitsu, soitsu, aitsu, doitsu こいつ, そいつ, あいつ, どいつ mean "this one," "that one (near you)," "that one (far from us)," "which one?" They're kosoado words that refer to individual items, and, sometimes, to people.
These words have nothing to do with itsu 何時, which means "when," or itsuka 何時か, "sometime."
In Japanese, kou, sou, aa, dou こう, そう, ああ, どう mean "this manner," "that manner (near you)," "that manner (far from us)," and "what manner?" They're kosoado words referring to manner.
In Japanese, konna, sonna, anna, donna こんな, そんな, あんな, どんな mean "like this [thing]," "like that [thing] (near you)," "like that [thing] (far from us)," and "like what [thing]?" They're kosoado words referring to how things are, or the appearance of things.
In Japanese, kocchi, socchi, acchi, docchi こっち, そっち, あっち, どっち mean "this way (toward me)," "that way (toward you)," "that way (away from us)," and "what way?" respectively. They're kosoado words related to direction, but they can also refer to sides, choices, and people.
The words kochira, sochira, achira, dochira こちら, そちら, あちら, どちら work the same way in some cases, but they're considered to be more polite.
In Japanese, kono, sono, ano, dono この, その, あの, どの mean "this," "that," and "what." They're kosoado words very much like kore, sore, are, dore これ, それ, あれ, どれ, except they're used as adjectives instead of as nouns.
The words sono その and ano あの are also interjections. The word dono どの after someone's name is the honorific dono 殿.
In Japanese, kore, sore, are, dore これ, それ, あれ, どれ mean "this thing (near me)," "that thing (near you)," "that thing (away from us)," and "what thing?" They're kosoado words that refer to things in general.
Sometimes, are? あれ？ is an interjection of doubt: "huh?"
In Japanese, kochira, sochira, achira, dochira こちら, そちら, あちら, どちら mean "this way (toward me)," "that way (toward you)," "that way (away from us)," and "what way?" respectively. They're kosoado words related to direction, but they can also refer to sides, choices, and people.
The words kocchi, socchi, acchi, docchi こっち, そっち, あっち, どっち are abbreviations of kochira, sochira, achira, dochira. They're used the same way in some cases, but they aren't considered as polite.
In Japanese, konata, sonata, anata, donata こなた, そなた, あなた, どなた are kosoado words related to direction, and then to person. They're a bit odd, because donata means "who," anata あなた is one of the various way to say "you" in Japanese, and the rest is archaic.
In various ways, they're similar to the words kochira, sochira, achira and dochira.
In Japanese, koko, soko, asoko, doko ここ, そこ, あそこ, どこ mean "here," "there (near you)," "over there (not near you)," and "where?" They are kosoado words related to place.
In Japanese, watashi 私, ore 俺, boku 僕, and various other words, all mean "I" or "me," that is, they're Japanese "first person pronouns," ichininshou daimeishi 一人称代名詞.
But why are there so many ways to say "I" and "me" in Japanese? What's the difference between them?
The basic gist is that some pronouns, like watashi, are used by women, while other pronouns, like ore and boku, are used by men, except that in business and formal contexts everybody uses watashi, except some men use boku or watakushi ワタクシ instead. It's complicated.
If you're learning Japanese and are unsure of what pronoun to use, just use watashi until you become sure.
