あり

あり is a colloquial expression derived from the verb ある (to exist / to have). It is used in two main ways: as a casual judgment meaning "acceptable / possible / an option", and in descriptions or listings to mean "with" or "having".

Expressing acceptability or possibility

In casual speech, あり is used to declare that something is acceptable, worth considering, or "a go." It functions almost like a noun or a na-adjective and is often paired with だ or です.

The opposite is なし, meaning "not an option" or "unacceptable":

In casual speech, あり can also modify a noun like a na-adjective using な:

Meaning "with" or "having"

あり is used in written descriptions, advertisements, and listings to indicate that something is included or present. This is common in job postings, real estate ads, and product descriptions.

Here, あり is the opposite of なし (without / not included): そうりょう送料あり (shipping included) vs. そうりょう送料なし (no shipping cost).

Nuances

This usage of あり is distinctly casual when used as a judgment. Avoid using it in formal writing or polite business settings. In the "with/having" sense for listings, it is standard and acceptable in any register.
