Learn Italian: Senza la moda, io non farei il sarto. - Without fashion, I would not be a tailor.

Fare is an irregular verb. Regular -are verbs change their "a" to an "e" in the conditional (for example, parlare becomes parlerei). But fare keeps its "a", making the "io" (I) form farei.

Why does the Italian use farei (I would make/do) when the English translation says "I would not be"?

In Italian, it is very common to use the verb fare to describe someone's profession. While you can say non sarei un sarto using essere (to be), saying non farei il sarto (literally "I would not do the tailor") is the most natural way to talk about working in a job.

Why is it il sarto (the tailor) instead of un sarto (a tailor)?

When you use the verb fare for a profession, you must use a definite article (il, la, etc.). If you used the verb essere instead, you would use the indefinite article just like in English: sarei un sarto (I would be a tailor).

Why is there a la before moda?

In Italian, broad categories and abstract concepts like "fashion", "nature", or "love" almost always require a definite article. English drops the article when speaking generally, but Italian keeps it.
