The Origin of Companies or Company’s

The word company comes from the Latin companio, meaning one who eats bread with another — essentially, a companion or group. Over time, it evolved to refer to a business organization.

Plural form: English simply adds -s to make most nouns plural: company → companies.
Possessive form: English uses ’s to indicate possession: company → company’s.

The distinction has remained clear in modern English, but learners often confuse plural forms with possessive forms because they sound similar when spoken.
