According to Ann Tarumoto’s book, そうです(soo desu) can mean ‘so I hear’, or ‘I understand that…’, depending on how it’s used.
To say ‘I hear it’s hot’, we can use the plain form of the verb hot さむい (samui), and add そうで.
Recall that the plain form of a verb is the less formal form. The plain forms for the adjective さむい (samui) are:
- さむい (samui) It’s cold.
- さむくない (samuku nai) It’s not cold.
- さむかった (samukatta) It was cold.
- さむくなかった (samuku nakatta) It wasn’t cold.
So, to say ‘I understand he is busy’ = いそがしい そうです (isogashii so desu).
