The spelling of the word "job halfdones" is not standard English. The correct spelling of the phrase would be "job half-done". The reason for this is that the word "half" is an adverb and is generally used with a hyphen when used to modify a noun. In IPA phonetic transcription, "job half-done" would be transcribed as /dʒɑb hæf dʌn/. The correct spelling of words is important for effective communication as it avoids confusion and misunderstandings.
