Adjectives ending in -s or -x change in the plural forms only when feminine

Look at these masculine cases:

un homme heureux et des hommes heureuxa happy man and happy men

un vent frais et des vents fraisa cool wind and cool winds

le gros chat et les gros chatsthe big cat and the big cats

Adjectives ending in-s and -x stay the same in masculine plural forms.

BUT

Look at these feminine cases:

une femme heureuse et des femmes heureusesa happy woman and happy women

une brise fraîche et des brises fraîchesa fresh breeze and fresh breezes

la grosse souris mais les grosses souristhe big mouse but the big mice

Note that the feminine plural forms of these adjectives are regular (add -s on the feminine singular form)

Incorrect heading

Not sure if this is an old link but despite a comment 2 years ago that the heading was incorrect, and a reply that it had been corrected, this page still misleadingly states the adjectives ending in s or x, only change their plural forms when feminine, rather than that they only change their form when feminine. Maybe just say they have 1 masculine and 2 feminine adjective forms!

It seems that the title of this lesson is incorrect, I believe it should read: "Adjectives ending in -s or -x change in the plural forms only when feminine" : )
