For example, when we say “each other’s work” it is a singular pluralization of the word form. When we say “consider other’s opinions,” we use “others'” with the apostrophe at the end with no additional “s” letter, because there are many opinions we are referring to.

Other’s and others’ are the possessive forms of “other.” We use other’s for singular possessive form (singular meaning one). For example: We couldn’t stop staring into each other’s eyes. We borrowed each other’s outfits. The students corrected each other’s homework. We use others’ for plural possessive form (multiple; more than one).

Other’s is the singular possessive form of other. E.g., “We must consider each other’s feelings.” Furthermore, the term others’ is the plural possessive. For example, “I passed, but the others’ results were terrible.” Finally, others is the standard plural form. The following chart shows the different forms of the word other.
