वैधता कम है और कल समाप्त होगी।

वैधता means validity or the period for which something remains valid.

In real-life Hindi, it is often used for things like:

• documents
• subscriptions
• IDs
• recharge plans
• tickets
• offers

So in this sentence, वैधता is the thing that is low/short now and will end tomorrow.

Here कम means less / short / low in amount.

With वैधता, it suggests that not much validity is left or the remaining valid period is short. This is especially common in practical contexts like phone plans, memberships, or expiry periods.

So वैधता कम है does not mean validity is morally or legally weak. It means:

• the valid period is short
• little validity remains
• the remaining duration is limited

A more explicit version could be:

• वैधता कम बची है = There is little validity left

But the original sentence is still understandable.

Because the sentence talks about two different times:

• वैधता कम है = The validity is low/short now → present
• कल समाप्त होगी = It will end tomorrow → future

So the first clause uses the present tense form है, and the second clause uses the future form होगी.

This is very normal in Hindi when one part describes the current situation and the next part describes what will happen later.

Because the implied subject is वैधता, and वैधता is a feminine noun.

In Hindi, verbs often agree with the gender and number of the subject, especially with forms like होगा / होगी / होंगे.

So:

• वैधता ... होगी → feminine singular
• if the noun were masculine singular, you would expect होगा

That is why समाप्त होगी is correct here.

Hindi very often leaves out pronouns when the subject is already clear from context.

In English, you would usually say:

• It will end tomorrow

In Hindi, once वैधता has already been mentioned, you can simply say:

• कल समाप्त होगी

The subject is understood automatically as वैधता.

A more explicit version would be:

• वैधता कल समाप्त होगी

But Hindi does not need to repeat it if the meaning is already clear.

समाप्त होगी means will end, will finish, or in this kind of context, will expire.

Breakdown:

• समाप्त = finished, ended
• होगी = will be

Together, it functions like will be over / will end.

In practical English, if this is about a plan, ticket, or subscription, the most natural translation is often:

• will expire tomorrow

So the Hindi is slightly more literal, but the real-world meaning is often expire.

It behaves like part of a verbal expression here.

The basic idea is from समाप्त होना, meaning:

• to end
• to be finished
• to expire

So समाप्त होगी is the future feminine singular form of that idea.

You can think of it as:

• [it] will become finished / will be finished
• more naturally: [it] will end

So while समाप्त can look adjective-like, in this sentence it is functioning as part of the predicate to end / be over.

कल can mean either yesterday or tomorrow. Hindi uses the same word for both, and the meaning depends on context.

Here it means tomorrow because the verb is future:

• समाप्त होगी = will end

So the sentence cannot mean ended yesterday. The future verb makes the meaning clear.

Hindi word order is often subject + description + verb, and time words like कल can appear before the verb.

So the structure is:

• वैधता = subject
• कम है = is low/short
• और = and
• कल समाप्त होगी = will end tomorrow

Hindi does not always place time words exactly where English does. English prefers:

• The validity is low and will end tomorrow

Hindi naturally allows:

• ... और कल समाप्त होगी

with कल before the ending verb phrase.

Yes, it is understandable, especially in formal or system-style language, but it can sound a little stiff depending on context.

Possible more natural alternatives include:

• वैधता कम बची है और कल समाप्त होगी।
  = There is little validity left and it will end tomorrow.

• इसकी वैधता कल समाप्त होगी।
  = Its validity will end tomorrow.

• वैधता कल खत्म हो जाएगी।
  = The validity will expire/end tomorrow.

Notes:

• समाप्त sounds a bit more formal.
• खत्म is more everyday and conversational.

So the given sentence is fine, but there are slightly more natural ways to say it.

और means and.

It joins the two clauses:

• वैधता कम है
• कल समाप्त होगी

So it connects:

• the present condition
• the future result

It works just like English and in this sentence.

Yes. A learner might find वैधता कम है slightly unusual because English more often says there is little validity left rather than validity is low.

Clearer Hindi alternatives:

• वैधता कम बची है = little validity remains
• केवल थोड़ी वैधता बची है = only a little validity is left
• वैधता जल्द समाप्त होगी = the validity will expire soon

The original sentence is not wrong, but these alternatives may sound more explicit.

Yes, somewhat.

The words वैधता and समाप्त are relatively formal or administrative in tone. You often see this style in:

• apps
• recharge messages
• official notices
• account/subscription information

A more conversational version might use:

• खत्म
• बची है
• चलने की अवधि

For example:

• इसकी वैधता कल खत्म हो जाएगी।
• बस थोड़ी वैधता बची है।

So the sentence sounds more like written/formal informational Hindi than everyday casual speech.
