Couple of points

Question

1. According to multiple references « faire du lèche-vitrines » is invariable with the plural form of 'vitrines'. However, it appears that the 1990 rectifications accept the singular form. The plural form is still correct but is being red-lined through the 's'.

2. The hint for "Some of them deliver to your door " is to use the plural form of "yours" - I think this is meant to be use the polite form, as the expected script is « votre porte », not « vos portes »

Accepted Answer

Hi Maarten, 
Thank you for bringing this to our attention. I have corrected the second error to 'use the polite form of your', and I will ask for the lèche-vitrines to be added but it is a holiday period and it might take some time.
Bonne Continuation!
