French language Q&A Forum

In this context, is suspecter inappropriate.   I considered soupçonner but my dictionary gave it as a second choice.  Are they not synonyms? 

Why is ce matin-là preferable to cette matinée and why is the latter not acceptable?  I thought that if you wanted emphasis on the morning, you would use matinée vice matin.  I realize that the là added to matin certainly adds the focus, but why is cette matinée not given as another possibility.   As you may have already surmised, I struggle with these masculine / feminine forms for morning, day, evening, year, etc. despite having reviewed the lesson.  Thanks for your guidance in advance.
