However, fountains do NOT come from animals. And "I have a feather pen", which would be a quill as used ages ago, was incorrect.
"plume d'oie" doesn't contain "stylo", but it means "quill pen". The French just express the idea slightly differently from English.
So " J'ai une plume d'oie" can mean BOTH "I have a goose feather" and "I have a quill pen"?
I know it's "mine not to reason why, mine but to do or die" but style plume as a foundation pen(?), when simple logic would assume since plume means feather it meant a quill pen. How do you say quill pen in French
They were the primary sort of pen before ballpoints came out, where there would be a nib, similar in a lot of ways to even older quill pens, attached to a cartridge which contained liquid ink, the ink would be drawn into the nib and could be written or drawn with. They are still used today and I have at least one. They are especially used for calligraphy, but need care as they tend to blot a lot more (hence the 'blotting pad' you may have encountered in older literature). It is a successor to the dipping pens where you had to dip the pen into ink continually, instead the pens had a 'fountain' of ink contained within the pen.
