यह काम आसान बन गया।

A word-by-word breakdown is:

• यह = this
• काम = work, task, or job
• आसान = easy
• बन गया = became

So the full sentence means This work became easy or This task became easy.

In this sentence, यह most naturally means this.

So यह काम = this work / this task.

In spoken Hindi, यह can sometimes also function like it depending on context, but for learners, it is best to read यह here as a demonstrative adjective: this.

Hindi does not have articles like a, an, or the.

So:

• काम can mean work, a task, the task, or the work
• The exact meaning depends on context

That is why यह काम can be understood as this work or this task without needing an extra article word.

Hindi word order is usually Subject + Object/Complement + Verb.

Here:

• यह काम = subject
• आसान = complement describing what the work became
• बन गया = verb phrase

So the structure is basically:

This work easy became

That is normal in Hindi. The main verb usually comes at the end.

आसान is an adjective meaning easy.

In this sentence, it describes the state that काम changed into. So it works like a predicate adjective, similar to easy in English The work became easy.

Also, आसान usually does not change form for gender or number in this kind of usage, so it stays आसान whether the noun is masculine, feminine, singular, or plural.

बन गया means became, not is.

So there is an important difference:

• यह काम आसान है। = This work is easy.
• यह काम आसान बन गया। = This work became easy.

The second sentence shows a change of state. It was not easy before, but now it has become easy.

बन गया comes from the verb बनना, which often means to become.

So:

• बनना = to become
• बन गया = became / has become

In this sentence, गया is not being understood literally as went. Together, बन गया functions as the past form of became.

Very often in learner-friendly translations, it is best to treat बन गया as one unit: became.

Because the subject here is काम, which is masculine singular in Hindi.

The past form agrees with that, so we get:

• masculine singular: गया
• feminine singular: गई
• masculine plural: गए

So:

• यह काम आसान बन गया। = This work became easy.
• यह बात आसान बन गई। = This matter became easy.
  (because बात is feminine)

Yes, काम is masculine in Hindi.

You often learn noun gender by exposure and memorization, because it is not always predictable from meaning. In this sentence, you can see the masculinity from the verb agreement:

• काम → masculine singular
• therefore बन गया

If the noun were feminine, the verb would change accordingly.

Yes, यह काम आसान हो गया is also very natural and very common.

Both can mean This work became easy.

A rough difference:

• आसान हो गया = became easy
• आसान बन गया = also became easy, sometimes with a slight sense of turned into or was made into / ended up becoming

In many everyday situations, हो गया is more common for change of state, but बन गया is still understandable and natural in the right context.

Yes. बन गया is a past/perfective form, so the sentence means that the change has already happened.

It tells you that at some point, the work became easy.

Depending on context, English might translate it as:

• became easy
• has become easy

In careful pronunciation, यह is often taught as yah.

In natural speech, many speakers pronounce it closer to yeh.

So learners will commonly hear:

• यह written
• pronounced something like yeh

That is normal. Hindi spelling and everyday pronunciation do not always match perfectly.

Sometimes, yes, depending on context.

काम can mean:

• work
• task
• assignment
• job

And आसान बन गया can mean became easy or in smoother English sometimes got easier, especially if the idea is that it used to be difficult.

But the most direct meaning is still This work/task became easy.
