About と同時に

To convey that things are happening at the same time in Japanese, と同時(どうじ)に will often be used. This is a combination of the case marking particle と in its listing particle use, 同時(どうじ), a noun meaning 'the same time', and に, the case marking particle marking a location.

と同時(どうじ)に translates as 'at the same time as (A)', 'the instant that (A)', or 'as well as (A)'. In sentences that use this grammar structure, (A) is considered to be the primary event, but any (B) or (C) events are not considered any less important.

In the case of nouns and な-Adjectives, である is often omitted.

While the literal meaning of と同時(どうじ)に is 'at the same time', this expression is also regularly used when listing multiple roles or functions that someone/thing has. This comes across as 'as well as', but still carries the 'at the same time nuance'.

    If と同時に uses the と listing particle, can we list various things before と同時に? There’s a difference in nuance in this case?

    I see it as more of a “together” particle here. Like サムと一緒に together with sam. With the same time as と同時に. Besides that I don’t know if it would work for multiple things. Another translation is “the instant” so not a lot of things can be done in that time frame. There’s probably better grammar to use in that case like 間に
