Η επιδότηση ισχύει υπό την προϋπόθεση ότι γίνεται έλεγχος.

ισχύει is the 3rd person singular of ισχύω. In this kind of sentence, it means is valid, applies, or is in force.

So Η επιδότηση ισχύει means something like the subsidy applies or the subsidy is valid.

It is a fixed, formal expression meaning on the condition that, provided that, or subject to the condition that.

This phrase is very common in official, legal, and administrative Greek.

The dictionary form is η προϋπόθεση. Here it becomes την προϋπόθεση because it follows the preposition υπό.

In Modern Greek, prepositions normally take the accusative, so:

• η προϋπόθεση = the condition
• υπό την προϋπόθεση = under/on the condition

By itself, υπό sounds formal or somewhat bureaucratic in Modern Greek. However, in the fixed phrase υπό την προϋπόθεση ότι, it is completely normal in official writing.

In everyday speech, people might prefer simpler alternatives such as αν or μόνο αν, depending on the context.

Literally, it means a check/inspection is happening or a check takes place.

Greek often uses γίνεται from γίνομαι in an impersonal way to mean that something takes place, happens, or is carried out.

So γίνεται έλεγχος is a natural way to say:

• an inspection is carried out
• a check is conducted
• there is an inspection

Not exactly in the same way English uses a passive.

γίνεται is the present form of γίνομαι, which means become, happen, or take place. But in English, the most natural translation is often passive-looking, such as an inspection is carried out.

So grammatically it is not simply the passive of κάνω, but in meaning it often overlaps with English passive expressions.

Because έλεγχος is being used in a general or indefinite sense.

So:

• γίνεται έλεγχος = an inspection is carried out / there is an inspection
• γίνεται ο έλεγχος = the inspection is taking place, referring to a specific inspection already known

No article here makes the statement more general.

The present tense here expresses a general rule or standing condition. This is very common in formal Greek.

So the sentence is not necessarily describing something happening right now. It is stating a rule: the subsidy applies under the condition that an inspection takes place.

If the speaker wanted to refer more clearly to a single future inspection, Greek might use a different structure, for example with αν γίνει έλεγχος or θα γίνει έλεγχος, depending on the exact meaning.

ότι introduces the subordinate clause after υπό την προϋπόθεση.

The structure works like English on the condition that...:

• υπό την προϋπόθεση ότι γίνεται έλεγχος
• on the condition that an inspection is carried out

So ότι is the normal linker in this pattern.

Yes, it sounds formal and administrative.

A more everyday version could be:

• Η επιδότηση ισχύει μόνο αν γίνει έλεγχος.
• Η επιδότηση δίνεται μόνο αν γίνει έλεγχος.

The original sentence is the kind of wording you might see in regulations, official notices, or application guidelines.

Here is the structure:

• Η επιδότηση = the subject
• ισχύει = the main verb
• υπό την προϋπόθεση = a prepositional phrase meaning on the condition
• ότι γίνεται έλεγχος = a subordinate clause explaining the condition

And inside that subordinate clause:

• γίνεται = the verb
• έλεγχος = the noun referring to the check/inspection

So the whole sentence is built as:

subject + verb + formal condition phrase + subordinate clause
