Learn Hardcore Romanian: Umplu un pahar cu apă rece și îl pun pe scaun. - I fill a glass with cold water and put it on the chair.

îl is the masculine singular direct-object clitic pronoun (3rd person). It refers back to un pahar (“a glass”), which is a masculine noun in Romanian. In English it corresponds to “it.” In the indicative mood, clitic pronouns are placed before the verb (proclitic).

Why do we say umplu un pahar cu apă and not some other preposition?

The verb a umple (“to fill”) takes the construction umple X cu Y – literally “fill X with Y.” Here cu means “with.” Other verbs might use în, la or no preposition, but a umple always uses cu to introduce what you’re filling something with.

Why isn’t there an article before apă rece, but there is one before pahar?

Pahar is a countable noun, so you need an indefinite article: un pahar. Apă, however, is an uncountable (mass) noun when speaking generally, so you don’t use an indefinite article before it. Hence apă rece (“cold water”) rather than o apă rece.

Why is the adjective rece placed after the noun apă? Can I say rece apă?

In Romanian the neutral word order is noun + adjective (e.g. apă rece, casă mare). You can move the adjective before the noun (rece apă) for emphasis or poetic style, but in everyday speech you almost always place it after.

Why is pe used before scaun? Can I use în or no preposition at all?

When you put something “on” a surface in Romanian, you use pe, not în. În means “in” or “inside.” Without any preposition you can’t express “on the chair”—you need pe, as in pe scaun.

Shouldn’t scaun have an article? Why not pe scaunul?

Here pe scaun is indefinite (like “on a chair” or “on the chair” in a general sense). You omit the article when you don’t need to specify which chair. If you want a specific, known chair, you’d say pe scaunul (with the definite article).

Is a comma needed before și in this sentence?

No. Because the two verbs (umplu and pun) share the same subject and the clauses are short, Romanian style omits the comma before și. Commas before și are optional when the structure is simple.

Why does the pronoun go before the verb (îl pun) instead of after like in pune-l?

In the indicative (and most other moods except the affirmative imperative), clitic pronouns are proclitic (they precede the verb): îl pun. In the affirmative imperative you use enclisis (attach after the verb): pune-l.

What’s the difference between pahar and ceașcă? When do I use each?

Pahar is a “glass” for water, juice, beer, etc. (typically made of glass). Ceașcă is a “cup” (usually porcelain or ceramic, with a handle) for coffee or tea. Use pahar for glasses, ceașcă for cups.
