The word "ployment" is not commonly used in English, but if it were, it would be spelled with a silent "p" as "employment." The IPA phonetic transcription for this word is /ɪmˈplɔɪmənt/. The "p" in the spelling is not pronounced, so it is omitted in the IPA transcription. The stress is on the second syllable, indicated by the accent mark. This word refers to the state of being employed or having a job.
"Ployment" is not a recognized word in the English language. It appears to be a typographical error or a made-up term. Therefore, there is no official dictionary definition available.
