I am allergic to nuts.
NOH-chee — the 'ci' makes a soft 'ch' sound. Allergico: al-LAIR-jee-ko.
State this clearly to waitstaff before ordering. Nut allergies can be life-threatening, so use this phrase firmly and follow with a question about specific dishes.
'Allergico' agrees with gender: allergico (male), allergica (female). 'Alle noci' uses the preposition 'a' + definite article 'le' contracted to 'alle'. In Italy, nuts often appear in pesto, desserts, and stuffings — always double-check.
Sono allergico alle arachidi.
I am allergic to peanuts.
Arachidi are peanuts, distinct from tree nuts (noci).
Ho un'allergia alle noci.
I have a nut allergy.
Noun form — 'un'allergia' with elision before vowel.
Questo piatto contiene noci?

Follow-up question to verify ingredients.
Italian law requires restaurants to declare the 14 major allergens on menus. Ask to see the 'scheda allergeni' (allergen sheet) if you need detailed information.
