Questions & Answers about Il s'agit d'une rumeur infondée.
Why use Il s'agit d'une... instead of C'est une... here?
How would I use the current lesson's grammar to say 'This is in no way an unfounded rumor'?
You would place ne and aucunement (or nullement) around the conjugated verb s'agit. The preposition de must still follow the negation: Il ne s'agit aucunement d'une rumeur infondée.
Where does the adjective infondée come from?
It is built from the past participle of the verb fonder (to found or base) combined with the negative prefix in-. It requires an extra -e at the end here to agree with the feminine noun rumeur.
Why is there a d' before une rumeur?
The fixed expression is il s'agit de. The preposition de is a mandatory part of the phrase, and it drops its vowel to become d' because the following word, une, starts with a vowel.
