Learn Farsi: کلی کار دارم.

کلی is a very common, colloquial way to say 'a whole lot of' or 'loads of' in spoken Farsi. While خیلی کار دارم is also completely correct, using کلی adds a bit more emphasis, like saying 'I have a ton of work.'

If the translation is 'loads of work,' why is کار (kār) in the singular form?

In Farsi, nouns that follow quantities, numbers, or measure words almost always stay singular. Because کلی already tells us there is a large quantity, making the noun plural (like کارها) is unnecessary and would actually be grammatically incorrect here.

Does کار دارم (kār dāram) mean 'I have a job'?

In everyday conversation, it almost always means 'I have things to do' or 'I am busy.' If you want to talk about having employment, you would typically use a word like شغل (shoghl) instead of just کار.

Can I put کلی (koli) after the noun, like we do with زیاد (ziyād)?

No, کلی acts as a quantifier and must come before the noun it describes (کلی کار). This makes its placement different from adjectives like زیاد, which usually come after the noun (کار زیاد).
