Most adjectives ending in -al change to -aux (masculine plural) or -ales (feminine plural) - see Forming the plural of adjectives ending in -al - but there are exceptions to that rule.
Look at these cases:
Ces tabourets sont bancals.
These stools are wobbly.
The following adjectives are exceptions which take -s in the masculine plural form:
| Masculine singular | Masculine plural | English |
| banal | banals | banal / ordinary |
| bancal | bancals | wobbly / rickety |
| fatal | fatals | fatal / lethal |
| naval | navals | naval |
| natal | natals | natal |
| glacial | glacials / glaciaux | freezing |
| final | finals / finaux | final |
ATTENTION:
Both plural forms of glacial and final are accepted in French: regular (glaciaux / finaux) and irregular (glacials / finals)
Il y a des vents glacials aujourd'hui!
There are some freezing winds today!
Les derniers jours ont été glaciaux !
The last days have been freezing !

.....except in the very rare case when the adjective "banal" us used in its other meaning: feudal (as in the "feudal system"). In that case the plural masculin is "banaux": "les moulins banaux" = the feudal mills where peasants could mill their grain paying a fraction of it to the lord of the land.

HI Dragana,
Indeed, these examples are all feminine and plural forms of adjectives-
Des pierres précieuses = Precious stones
Des averses glaciales = Icy showers
Des boissons fraîches = Cold drinks
Des chemises chères = Expensive shirts
Des pommes rouges = Red Apples
Hope this helps!

Thank you Alan. That is exactly what I was asking. So fatal is fatales in Feminine Plural.
