Learn Italian: Chi inganna la gente perde sempre. - Whoever deceives people always loses.

The pronoun chi always takes a third-person singular verb, even when it translates to a plural concept like "those who" or "the people who" in English. Therefore, we use the singular forms inganna and perde.

Why is it la gente (singular) instead of a plural word for "people"?

In Italian, la gente is a singular feminine noun, functioning much like the English word "the crowd". You will generally use this singular form rather than a plural like le persone unless you are talking about a specific, countable number of individuals.

Does chi act as the subject for both verbs in this sentence?

Yes! Chi is a special relative pronoun because it merges the roles of "the person" and "who". Here, it acts as the subject of the first verb (inganna) and also provides the subject for the main clause's verb (perde).

Why is it perde sempre instead of sempre perde like "always loses" in English?

In Italian, adverbs of frequency like sempre (always) usually come immediately after the verb they modify, whereas in English they typically come before it.
