altele

In a sentence

• Unele cărți sunt vechi, altele sunt noi.

  Some books are old, others are new.

  Here, 'altele' is used as a pronoun to refer to 'cărți' (books) already mentioned, emphasizing the distinction between different subsets.

• Am cumparat mere roșii, iar altele galbene.

  I bought red apples, and others, yellow ones.

  'Altele' replaces the noun 'mere' (apples) mentioned earlier while indicating differentiation by color.

• Nu am terminat toate sarcinile, mi-au rămas altele de făcut.

  This usage of 'altele' signifies remaining tasks distinct from those already completed, standing in for the noun phrase 'sarcinile' (tasks).
