The phrase "art sure of" may initially seem straightforward, but its spelling can be tricky due to the silent "h" in "sure." Phonetically, "art sure of" is transcribed as /ɑrt ʃʊr ʌv/. The "a" sound in "art" is pronounced like the "a" in "father." The "sh" sound in "sure" is pronounced like the "sh" in "shoe." The "u" sound in "sure" is pronounced like the "u" in "put." The word "of" is pronounced like it looks, with a short "o" sound followed by an "f" sound.
