として

The particle として is used after a noun to express "as," "in the role of," or "in the capacity of." It indicates the role, status, position, or function in which a person or thing acts or is regarded.

Expressing a role or capacity

The most common use of として is to describe the role or position someone holds when doing something.

Here, として clarifies in what capacity the action is being performed.

Expressing how something is regarded or treated

として can also indicate how something is perceived, treated, or classified.

Expressing a standpoint or perspective

として can mark whose perspective or standpoint is being expressed, often translating to "from the standpoint of" or "as (someone)."

としても – even as

When combined with も, としても means "even as" or "even in the role of," adding a concessive nuance.

Related expression: としては

Adding は after として creates としては, meaning "for (something in that category)" – used to evaluate something relative to expectations for that role or category.
