I read in a Japanese Grammar(*) written in French:
息子【むすこ】は元気【げんき】で,私達【わたしたち】も安心【あんしん】した.
~ "My son is healthy, and we feel reassured". (translation from the French translation given by Reiko Shimamori: "Mon fils est en bonne santé, et nous en sommes rassurés.")
What's the exact meaning of も in this sentence?
Since も doesn't coordinate propositions, this particle can't mean "my son is healthy and we feel reassured". I don't think も stands for "(we) too" as in "my son is healthy and we too feel reassured".
Reiko Shimamori writes somewhere in her book that も may have an "emphatic meaning" but I can't find the reference.
Any idea to help me?
