"We are working."

Translation: हम काम कर रहे हैं।

[DanaSavage]

Why is हम काम कर रही हैं incorrect?

[vinay92]

It is correct when the group comprising हम is made up of only women. You can report it if you see the sentence again.

That said, it is increasingly common to use only the रहे form with हम even for an entirely female group even if it is not technically correct.

[M.S.VIGNESH]

Why is ham kaam karthey hai wrong ?

[vinay92]

हम काम करते हैं would be 'We work'. It's in the simple present tense and is conveying that we work (generally or habitually) but may not be working at this moment.

हम काम कर रहे हैं / 'We are working' is in the present continuous tense and is saying that we are currently working at this time.

[GraysonElliott]

Since this is actually saying "we work do ing are", or "we are doing work", rather than "we are working", is this because काम is only a noun and there's actually no stand-alone verb for "work" in Hindi? We never work—we instead do work?

[vinay92]

Correct. The verb करना is often added to nouns and adjectives to make them into verbs.

For example,
काम करना = to do the work = to work
पसंद करना = to do the liking = to like

In conversational Hindi (and Hinglish), करना is also added to foreign (mostly English) verbs to make them fit into a Hindi sentence.
Eg: मैं अब ड्राइव कर रहा हूँ = I am driving now

Dear vinay92: how does it feel to be so awesome?

Thank you!

Is हम कर रहे हैं। correct also? It was refused by DL.

[vinay92]

हम कर रहे हैं। would just be "We are doing (it)". काम is the word for 'work'
