ある

1. Origins, structure, and basic meaning

• Structure: A basic existence sentence marks the place with に, the existing thing with が, and ends with ある. The polite form is あります.
• Basic usage: It expresses the presence of objects or plants, or the availability of scheduled events, opportunities, and similar things.
  • 机の上に辞書があります。 introduces the presence of a dictionary on the desk.

2. Common pitfalls and similar expressions

• What is there and where it is
  • 机の上に辞書がある introduces what exists there. 辞書は机の上にある explains the location of a dictionary already made the topic.
• Types of referents compared with いる
  • People and animals normally take いる, but plants take ある, as in 庭に花がある. Dividing expressions solely into living and nonliving things can lead to the wrong choice for flowers.
• Negative forms
  • The plain negative is ない, and the polite negative is ありません. Learn ある separately from the regular negative-form pattern of other verbs.
