İskenderun's primary language is Turkish, but Hatay Province retains a strong Arab cultural identity, and Levantine Arabic is commonly heard in bazaars, older neighborhoods, tea gardens, and family-run lokantas. Locals often switch between Turkish and Arabic mid-sentence, so recognizing a handful of each helps in markets around the harbor, in Arsuz-bound minibuses, and in neighborhoods like Denizciler and Sarıseki.
Carry a small pocket phrase list or use Google Translate's camera feature on menus printed in Arabic. Turks are forgiving of mispronunciation, and a simple Merhaba plus eye contact goes far. For emergencies, the countrywide 112 line handles police, ambulance, and fire across all languages, with Turkish and Arabic operators available in Hatay.
