The phrase "art through with" has a unique spelling. The first word, "art," is spelled as it appears in standard English. However, the pronunciation of the second word is a bit more complex. It is spelled "through" but is pronounced with a voiced "th" sound (/ð/) followed by an "oo" sound (/uː/), and ends with a voiceless "th" sound (/θ/). The word "with" is spelled as expected, but the entire phrase can be confusing for non-native speakers due to its irregular pronunciation.
