एकल मुश्किल है।

एकल is a fairly formal Hindi word meaning single, solo, lone, or individual. It often sounds more abstract or official than everyday vocabulary.

A learner will usually hear अकेला / अकेली much more often in normal conversation when the idea is alone.

It is understandable, but it does not sound very natural in everyday speech.

Why?

• एकल is somewhat formal/bookish.
• The sentence is very compressed.
• Hindi speakers would usually make the idea more explicit.

More natural versions depend on the intended meaning:

• अकेला होना मुश्किल है। = Being alone is hard.
• अकेले रहना मुश्किल है। = Living alone is hard.
• एकल जीवन मुश्किल है। = Single life is difficult.
• अविवाहित रहना मुश्किल है। = Being unmarried is hard.

So the original sentence is possible, but it feels bare and slightly unnatural.

Not exactly.

• एकल = single / individual / solo
  This is more formal and often used in fixed expressions or official language.
• अकेला = alone / by oneself / lonely
  This is much more common in everyday Hindi.

So they can overlap in some situations, but they are not perfect substitutes.

For example:

• अकेला आदमी = a man who is alone
• एकल प्रदर्शन = a solo performance

Also, अकेला can suggest emotional or physical aloneness, while एकल usually does not.

Sometimes, but it is not the most common everyday word for that.

If you mean single / not married / not in a relationship, Hindi speakers often use:

• अविवाहित = unmarried
• सिंगल = single, in modern colloquial Hindi
• sometimes a fuller phrase depending on context

So if the intended meaning is being single is hard, एकल may sound too formal or slightly unnatural by itself.

Here मुश्किल is functioning like an adjective in the predicate:

• X मुश्किल है = X is difficult / hard

But मुश्किल can also act like a noun in other contexts, meaning difficulty or problem.

Compare:

• यह काम मुश्किल है। = This work is difficult.
• एक मुश्किल है। = There is a problem / difficulty.

So in your sentence, it means difficult / hard.

Because मुश्किल is an indeclinable adjective in normal use. That means it usually stays the same instead of changing for gender or number.

Compare with a changing adjective:

• अच्छा लड़का
• अच्छी लड़की

But with मुश्किल:

• काम मुश्किल है।
• ज़िंदगी मुश्किल है।
• सवाल मुश्किल हैं।

The word मुश्किल stays the same. What may change is the verb:

• है for singular
• हैं for plural or respectful subjects

Because standard Hindi word order usually puts the verb or copula near the end of the sentence.

So the structure is:

• एकल = subject/topic
• मुश्किल = predicate
• है = is

This is very normal in Hindi. English says:

• X is difficult

Hindi often looks more like:

• X difficult is

That is a very natural question.

This sentence is quite compressed. Hindi can sometimes express an idea in a short, compact way without explicitly adding होना.

But if you want to make the idea clearer, Hindi often does use होना:

• एकल होना मुश्किल है।
• अकेला होना मुश्किल है।

And in everyday speech, speakers may prefer an even more natural version such as:

• अकेले रहना मुश्किल है।

So the missing being is one reason the original sentence feels short and somewhat formal or unnatural.

A simple learner-friendly pronunciation is:

ekal mushkil hai

A few notes:

• एकल ≈ eh-kul or ay-kul
• मुश्किल ≈ moosh-kil or mush-kil
• श sounds like sh
• है is commonly written hai in transliteration

You do not need perfect pronunciation right away; the main thing is to keep मुश्किल as two clear parts: mush + kil.

That punctuation mark is called the danda.

It works like a period/full stop in Hindi:

• । = .

So एकल मुश्किल है। simply ends with the standard Hindi sentence-ending mark.
