Pronunciation: [wɒz kˈiːn ˈɒn] (IPA) 
The three words "was keen on" are a great example of English spelling challenges. The first word, "was," is pronounced /wʌz/, with the "a" pronounced like "uh." The second word "keen" is pronounced /kiːn/, with a long "e" sound and a silent "e" at the end. Finally, "on" is pronounced /ɒn/, with the "o" sound like "aw." Despite these challenges, proper spelling is crucial for clear communication in written English.
"Was keen on" is a colloquial expression used to describe a strong interest or desire towards something or someone. Derived from the adjective "keen," which means having a strong and enthusiastic desire or interest in someone or something, when combined with the preposition "on," it intensifies the meaning and emphasizes the individual's strong inclination or liking.
