ございます (gozaimasu) — the very polite, humble-register version of あります, heard constantly in shops, restaurants, and customer service. Example: こちらにございます (Kochira ni gozaimasu — It's right here [very formal]). You'll also recognize it from ありがとうございます (arigatou gozaimasu — thank you), which literally contains this form.

おありになる (o-ari ni naru) — the honorific form, used to describe something belonging to or connected with a person you're showing respect to. Less common in daily speech, more common in very formal writing or announcements.

あります (arimasu) = "ah-ree-mah-soo" (stress on first syllable)

ありました (arimashita) = "ah-ree-mah-shee-tah" (stress on first syllable)

ある (aru) = "ah-roo" (short, like "ah" + "roo")

あった (atta) = "aht-tah" (crisp double consonant)

ない (nai) = "nai" (rhymes with "bye" + "eye")

Japanese splits "to be" by animacy: ある (aru) for inanimate things (objects, places, events, abstract ideas) and いる (iru) for animate things (people, animals). "ペンがある" (pen ga aru — there is a pen) vs. "猫がいる" (neko ga iru — there is a cat).

ある is almost perfectly regular, but its negative breaks the pattern: it's ない (nai), not the expected あらない (aranai). ない then conjugates like an い-adjective: なかった (nakatta — wasn't), なくて (nakute — not being). This is the single quirk to memorize about ある.

Unlike いる's 〜ている (ongoing action), ある's te-form combination 〜てある (te aru) describes a deliberate, lasting result of someone's action: "窓が開けてある" (mado ga akete aru — the window has been opened [and left that way]). It implies intent — someone did this on purpose and the result persists.

Japanese doesn't have a direct verb "to have" for most possession — instead it says the thing exists for you: 車があります (kuruma ga arimasu — I have a car, lit. "a car exists"), お金がありません (okane ga arimasen — I don't have money). The person is marked with は or omitted, and the possessed thing takes が.

ございます (gozaimasu) is everywhere in Japanese customer service — shop clerks, hotel staff, and train announcements use it instead of あります. You already know a piece of it from ありがとうございます (arigatou gozaimasu — thank you very much), which is built on this same polite root.
