Google tells me that a péniche is a barge - a massive industrial transport - and a pénichette is a vessel used for recreation. Google is, of course, notoriously untrustworthy - what are your thoughts?
I'd forgotten that (certain) adjectives that modify proper nouns precede the noun - charmant village de Trève - so reviewed the lesson on "More Adjectives that go BEFORE the noun". Having done that, I then entered "le paisable historique hameau" ... only to find that historique should follow the noun. Google (yes again) tells me that qualifying and expressive adjective precede a common noun, while objective and classifying nouns do not. Maybe add more of an explanation to the lesson?
Merci!
