When other as a pronoun refers to more than one person or thing, it takes the plural form, others: Some scientists think we should reduce the number of flights to prevent global warming; others disagree. Not: … other disagree. Other must have a determiner before it when it comes in front of a singular countable noun.

Both are pronouns, that is, they stand for a noun. ‘Others’ is more vague, we are not determining how many others, or which other ones. ‘The others’ is more specific; it stands for all the rest.

Others is only used as a pronoun. But 'other' has different grammatical functions. On the other hand, 'others' refers to more than one; while 'other' refers to only one thing.

Other vs others We normally use other + plural noun. I want to see other shops before deciding. Others is a pronoun, i.e. not followed by a noun. A lot of volunteers have joined us, but we need to find others.

When you have many choices, you talk about one, another, another, and finally the other. “The other” signals the last alternative or item. When you have only two choices, you talk about one and the other. Again, “the other” signals the last alternative or item.
