Imperative of *dire*
Use *Dis* (2nd person singular) for a direct command; *dit* is the past participle and is incorrect here.
Preposition *à* + definite article
When the noun begins with a vowel, *à le* contracts to *à l'* (e.g., *à l'hôte*).
Contraction *l'hôte*
*l'hôte* can refer to a male or female host; the article contracts with the vowel‑initial noun.
Conditional clause with *si*
*si* introduces a condition (if); it does not change the verb tense that follows.
Present tense of *avoir*
*as* is the 2nd person singular present of *avoir* (to have).
Partitive article *des*
*des* is the plural partitive article used before an indefinite plural noun like *allergies*.

✕Common Mistakes

Cultural Tip
In French‑speaking countries, it is considered courteous to disclose any food or medication allergies to the person hosting you, especially in hotels or at a private dinner. The word *hôte* is gender‑neutral; if you know the host is a woman, you can also say *l'hôtesse*. Using the imperative *Dis* shows confidence but remains polite when followed by *s'il te plaît* or a friendly tone.
