Learn Farsi: زود رسیدن به هتل خیلی مهم است. - Arriving early at the hotel is very important.

To find the past stem of any Farsi infinitive, you simply drop the final ن (n) at the end of the word. For رسیدن (to arrive), dropping the ن gives you the past stem رسید (resid). You will use this base to build past tense verbs.

The translation says arriving, but isn't رسیدن the infinitive to arrive?

Yes, it is! In Farsi, infinitives can act as nouns, just like words ending in -ing (gerunds) do in English. When an action is the subject of the sentence, Farsi uses the full infinitive, so رسیدن can mean both to arrive and arriving.

Why does the sentence use به (to) before the hotel instead of a word for at?

In English, we say we arrive at a place. However, the Farsi verb رسیدن pairs with the preposition به (to) to show destination. You can think of it as literally saying arriving to the hotel.

Why does the word زود (early) come before رسیدن (arriving)?

In Farsi, adverbs like زود (early) generally come right before the verb or the verbal noun they are describing. This is why the sentence says زود رسیدن (early arriving) rather than the English order of arriving early.
