How to say "visa" in Arabic

taʾshīra looks tailor-made to match Hebrew א-ש-ר, the root behind אישור 'approval' and אישר 'to authorize' — same three letters, same sound. But the regular sound correspondence points the other way: Arabic ش normally lines up with Hebrew שׂ (sin), not the שׁ (shin) of אשר, which properly matches Arabic س or ث. So despite the tempting resemblance, these likely aren't the same Proto-Semitic root — a classic trap for a Hebrew speaker, since שׁ and ש both just sound like 'sh'. Worth knowing as a mnemonic, not as an etymology.
