Tento plán má smysl.

Tento means this.

A useful rough distinction is:

• tento = this / this specific
• ten = often that, but in everyday Czech it can also function a bit like the or a less emphatic this/that, depending on context

So Tento plán is a clear, textbook-style way to say this plan.

In everyday speech, you may also hear Ten plán má smysl, but that can sound a little different in nuance depending on the situation.

It is in the nominative case, because it is the subject of the sentence.

• plán = a masculine inanimate noun
• tento changes to match the noun in gender, number, and case

So:

• nominative masculine inanimate singular: tento plán

That is the form you use for this plan when it is the thing doing the action or being described.

Because Czech uses the expression mít smysl, literally to have sense, to express the idea to make sense.

So:

• má = has
• smysl = sense / point / meaning

Literal translation:

• This plan has sense

Natural English translation:

• This plan makes sense

Using je here would not be idiomatic.

Má is the 3rd person singular present tense form of mít (to have).

So the present-tense forms are:

• já mám = I have
• ty máš = you have
• on/ona/ono má = he/she/it has

Since plán is singular, you use má.

It is in the accusative, because it is the direct object of má in the phrase mít smysl.

However, there is something important to notice:

• smysl is a masculine inanimate noun
• in the singular, the nominative and accusative forms are the same

So although it is accusative here, it still appears as smysl.

Very often, yes, but it can also mean something like:

• be worthwhile
• have a point
• be meaningful

So má smysl is a little broader than just logical makes sense.

Examples:

• To má smysl. = That makes sense. / That’s worthwhile.
• Nemá to smysl. = It doesn’t make sense. / It’s pointless.

Context tells you which English translation fits best.

Both can often be translated as makes sense, but there is a slight tendency:

• dává smysl = often about something being logically understandable or fitting together
• má smysl = often about something having a point, being sensible, worthwhile, or justified

In many real situations, the two overlap.

For example:

• To dává smysl. = That makes sense.
• To má smysl. = That makes sense. / That has a point. / That’s worthwhile.

With plán, Tento plán má smysl sounds very natural.

Yes. Czech word order is flexible, but the basic neutral order here is:

• Tento plán má smysl.

That is the safest form for learners.

Other word orders are possible for emphasis or contrast, for example:

• Smysl má tento plán.
• Má tento plán smysl? = Does this plan make sense?

So yes, word order can change, but the neutral statement is the one you were given.

Negative:

• Tento plán nemá smysl. = This plan doesn’t make sense. / This plan is pointless.

Question:

• Má tento plán smysl? = Does this plan make sense?

In Czech, negation is often made by adding ne- to the verb:

• má → nemá

The verb má smysl stays the same if the noun is still singular, but the demonstrative changes to match the noun’s gender.

Examples:

• Tato myšlenka má smysl. = This idea makes sense.
  (myšlenka is feminine)

• Toto řešení má smysl. = This solution makes sense.
  (řešení is neuter)

So the pattern is:

• masculine: tento
• feminine: tato
• neuter: toto

Because Czech has no articles.

Unlike English, Czech does not normally use separate words for a/an or the.

So:

• plán can mean a plan or the plan, depending on context
• tento plán clearly means this plan

Czech relies on context, word order, and words like tento to show definiteness or emphasis.

A simple learner-friendly approximation is:

• TEN-to plaan maa SMI-sl

A few notes:

• te in tento is like te in ten
• á in plán and má is a long vowel, so hold it a bit longer
• y in smysl is pronounced roughly like a short i for most learners
• smysl is the trickiest word; the final l is pronounced clearly

Also, Czech stress normally falls on the first syllable of each word:

• TEN-to
• PLÁN
• MÁ
• SMY-sl

You do not need perfect pronunciation right away; being able to say Tento plán má smysl clearly and with a long á is already a very good start.
