Learn Romanian: Gâtul lui este curat.

In Romanian, the word for 'the' (the definite article) is usually attached to the very end of the noun. Gât means 'neck', and adding the suffix -ul makes it gâtul, which translates to 'the neck'.

If the sentence means 'his neck', why does it literally say 'the neck' (gâtul)?

When you use a possessive word like lui (his), Romanian grammar requires the noun it belongs to to have the 'the' ending attached to it. So, you literally say 'the neck his' to mean 'his neck'.

Why does lui come after the noun rather than before it?

Unlike English, Romanian places possessive words like lui (his) and ei (her) immediately after the noun they describe. This is why the sentence is ordered as Gâtul lui instead of Lui gâtul.

Would the word curat (clean) change if we were talking about a different body part?

Yes! Adjectives in Romanian have to match the gender of the noun they describe. Gât behaves like a masculine noun in the singular, so we use the basic form curat. If we were talking about a feminine noun like mâna (the hand), we would add an 'ă' to make the adjective feminine: mâna lui este curată.
