Solution:Abound (Verb) = प्रचुर मात्रा में होना (exist in large numbers or amounts).Lack (Verb) = अभाव होना, कमी होना (the state of being without or not having enough of something; scarcity; shortage).
Suffice (Verb) = पूरा करना, तृत्प करना, काफी होना (be enough or adequate; satify; satiate; complete).
Shine (Verb) = चमकाना, प्रकाशित करना (give out a bright light; glow; glitter).
Failure (Noun) = असफलता, नाकामयाबी (lack of success; flasco; set back).
अतः abounds का antonym lacks है।
