The word "proportionatelies" is not a commonly used word in English, but it is the plural form of the adverb "proportionately". It is spelled with three syllables: pro-por-tion-ate-lyz, and pronounced as /prəˈpɔːʃənətliːz/. The IPA phonetic transcription shows that there is emphasis on the middle syllable with a short "o" sound. The "ly" suffix is added to turn the adjective "proportional" into an adverb, meaning "in a proportional manner".
