"les émissions de sport sont affreux." what is grammatically wrong with this sentence? jess

the main subject  is "Les émissions -de sport- "

les émissions is the plural of l'émission or une émission = feminine noun

so the adjective "affreux" has to be feminine/plural as well

Les émissions de sport sont affreuses is the correct sentence

if it had been "les reportages de sports sont affreux" it would have been correct because "le/un reportage" is masculine and affreux is ok for masculine singular and plural

affreux (masculine singular and plural) 
affreuse (feminine singular) //affreuses (feminine plural)

hope it was clear enough to help you !!

Les émissions de sport sont affreuses.
Les émissions de sport : sujet (féminin/pluriel)
Sont : verbe "être" au présent
Affreuses : adjectif (féminin/pluriel)
