-lui m/n

1. (definite article) the (masculine/neuter singular, genitive and dative)

This form of the definite article is used for both masculine and neuter nouns in the genitive and dative cases which end in a vowel (including -e, but not -i):

• tatălui, from tată, masc.
• fiului, from fiu, masc.
• fratelui, from frate, masc.
• numelui, from nume, neut.
• soarelui, from soare, masc.

The suffix is also used with masculine and neuter singular adjectives in the genitive and dative cases to make the articulated definite form, often for emphasis, and it is used before the noun it modifies.

• osul iutelui câine, from osul câinelui iute (both meaning, "the swift dog's bone")

• lui
