Example sentence

Until the third day came,
الْثَّالِثَ third
An ordinal adjective, 'third', matching the day-noun before it in being definite and in case so it reads as part of the same phrase. Arabic ties a describing word to its noun by echoing those features.

How it is used
Thālith is the ordinal built on the root's number-verb ثَلَثَ, following the same pattern used for other ordinals (classical usage has a horse or rider come ثالث after the leader, then رابع 'fourth', then خامس 'fifth'). With the article it gives 'the third' (aṯ-ṯāliṯ), and it can take a following count to mean 'third of...', echoing the verb's sense of joining two others to make three.
