If we look at the latter meaning: it is an adjective which is used to refer to the second two previous things. Latter can be used in a sentence in two rationales. The first one is to use the word latter to refer to the last two items, which are in sequence. “The roots can cause cracks in the foundation and sidewalks. The latter structural condition concerns future homeowners.” The second one is to use the latter in a list with longer than two items. For example,” make a tea with spices, lemon juice, and some fresh mint leaves. You can substitute the cardamom leaves for the latter.
