Pronunciation: [ˈɔːl ɐ pˈiːs] (IPA) 
The phrase "all a piece" is sometimes spelled as "all in one piece". It means to be complete, undivided or intact. The IPA phonetic transcription for "all a piece" is /ɔːl ə piːs/, and for "all in one piece" it is /ɔːl ɪn wʌn piːs/. The spelling of "a" instead of "in" is likely due to phonological reduction, where the "n" sound in "in" is dropped in casual speech.
The phrase "all a piece" is an idiomatic expression used to describe a situation where two or more things or people are virtually indistinguishable or interchangeable. It implies that all the objects or individuals under consideration share the same characteristics, qualities, or attributes, thereby making them equal or similar in nature.
The term "all a piece" is often employed to convey a sense of uniformity, unity, or equality. It suggests that there is no significant difference or discrepancy between the various elements being discussed. It can be used in various contexts, such as describing two identical things, similar opinions or ideas, or even individuals who have comparable abilities or talents.
The phrase can also be used metaphorically to describe situations where two or more outcomes or alternatives have essentially the same effect or result. In this sense, it suggests that the options available are so similar that choosing one over the other would make no real difference in the final outcome.
For example, if someone says, "Both cars are all a piece; it doesn't matter which one you choose," they are implying that both cars are identical in terms of quality, performance, and suitability. Similarly, if someone states, "Their opinions are all a piece," they mean that the views or perspectives being expressed are largely the same and do not significantly differ from one another.
In summary, "all a piece" refers to a state of uniformity, similarity, or indistinguishability, where the various objects, ideas, or individuals being considered are essentially identical or possess similar qualities.
