The spelling of the phrase "it a dealt" can be confusing due to the irregularity of English pronunciation. In IPA phonetic transcription, the word "it" is written as /ɪt/, while "a" is transcribed as /ə/. However, when these two words are pronounced together, they form a unique sound /ɪdə/, which is represented in written English as "it a dealt." It is important to note that the spelling of this phrase may vary depending on the speaker's accent and dialect.
