〜と同時に~to douji ni

How it works

1. 

   The same phone has two qualities at once. Here, the pattern is about more than when an action happens.

2. 

   The two events share one clock: the product sells out as soon as it goes on sale, emphasizing that they happen almost at the same instant.

3. 

   Attach the pattern directly to the plain form of verbs and い-adjectives. The examples use 「広げる」 and 「見やすい」.

4. 

   Nouns and な-adjectives often take 「であると同時に」, as in 「便利であると同時に」.

5. 

   Nouns marking a starting point in time can take the pattern directly. 「発売と同時に」 means at the very moment something goes on sale.

6. 

   In the SNS example, the benefit and the risk coexist. This pattern can also connect two contrasting sides.
