This is the 638th most frequent Romanian word.
altele
"Altele" means "others" in English.
'Altele' replaces the noun 'mere' (apples) mentioned earlier while indicating differentiation by color.
Am cumparat mere roșii, iar altele galbene.
I bought red apples, and others, yellow ones.
This usage of 'altele' signifies remaining tasks distinct from those already completed, standing in for the noun phrase 'sarcinile' (tasks).
Nu am terminat toate sarcinile, mi-au rămas altele de făcut.
I haven't finished all tasks; I still have others left to do.
Here, 'altele' is used as a pronoun to refer to 'cărți' (books) already mentioned, emphasizing the distinction between different subsets.
