u have mentioned gentil and gros as irregular adjectives but truly it comes under one rule which is when an adjective ends with on, s and l the last letter gets doubled and an e is added although you mentioned the spelling correctly and the feminine form also correctly but they don't come under irregular
@@meghanagarg9697 yes, but it is different from the other categories of adjectives. Similarly , adjectives ending with 'n' also add one more n and e like bon, mignon so these are also a separate category different from other rules.
