I've been working for two days straight - is it the correct word order?

[Emmaprad]

Hi everybody
I'm an italian girl. Could anyone help me to understand this expression:

I've been working for two days straight

if the word "straight" was an adjective, it would be placed before the name, wouldn't it? but in this case? so, which is "straight" ?

Thank you for helping me!

Hi and welcome to the forum, Emma!

You're right, adjectives are placed before the noun in English. In your sentence, however, 'straight' is used as an adverb and means 'non-stop'.

Ciao and see you again soon!

thank you very much for your explanation, conchita (and pleased to meet you!)
