Questions & Answers about मेज़ की सतह साफ है।

What is the grammatical breakdown of मेज़ की सतह साफ है?

A natural breakdown is:

• मेज़ = table
• की = of / possessive marker
• सतह = surface
• साफ = clean
• है = is

So the structure is basically:

• मेज़ की सतह = the table’s surface / surface of the table
• साफ है = is clean

A very literal word-for-word order would be:

table of surface clean is

Hindi often builds possession this way: X का/की/के Y = Y of X / X’s Y.

Why is it की and not का or के?

Because का/की/के agrees with the noun that comes after it — the thing being possessed — not with the possessor.

Here, the possessed noun is सतह (surface), and सतह is feminine singular, so Hindi uses की.

Compare:

• मेज़ की सतह = the table’s surface
  (सतह = feminine singular, so की)

If the following noun were masculine singular, you would use का.
If it were plural (or masculine plural), you might use के.

This is one of the most important things to remember about का/की/के.

Does की agree with मेज़ or with सतह?
