Questions & Answers about O gajo da loja ajudou-me muito.
Is gajo considered polite, or is it slang?
It is definitely informal slang, very similar to "guy" or "bloke" in English. While it isn't a swear word, you shouldn't use gajo (or the feminine gaja) in formal or professional situations, as it can sometimes sound a bit disrespectful or overly casual. In casual conversation among friends, however, it is extremely common in Portugal.
Why is the pronoun attached to the end of the verb (ajudou-me) instead of coming before it?
In European Portuguese, the default rule for affirmative main clauses is to place the object pronoun after the verb, connected by a hyphen. If there were a "magnet word" earlier in the sentence, such as a negative word like não or a conjunction like que, it would pull the pronoun before the verb to make não me ajudou.
The English translation says "from the shop", but the sentence uses da (de + a). Could I say na (em + a) instead?
Using da loja (literally "of the shop") specifically identifies which guy you are talking about, implying he works there or is associated with it. If you said na loja, it would mean "The guy helped me a lot inside the shop", which changes the focus to where the helping action happened rather than identifying the person.
Why doesn't muito change gender or number here?
