としてAs (i.e. in the role of), For

When the case marking particle と is used to highlight a result, it regularly translates to 'as' in English. This nuance of 'as' simply assumes that (A) is a plain or unchanging fact from which something (usually an opinion or evaluation) is based. Combining this nuance of と with して (the conjugation form of する), として will present (A) as the base point from which (B) can be determined.

Despite being a combination of several individual parts, として is often considered to be a 副助詞(かくじょし) (adverbial particle) by itself, meaning that it will most often be seen connected directly to nouns.

As として works in the same way as a 副助詞(かくじょし), it may be connected directly to a second noun to express that (B) is something functioning as (A).

Fun Fact

This result use of と regularly appears when one particular aspect of something is being highlighted (while other aspects still exist). This simply means that nothing apart from (A) is being considered when expressing (B).
