Why "children," not "childs"? (2016)
The article explores the historical reasons behind irregular English plurals like "children" instead of "childs," tracing their origins to Old English declensions and the suffix "-en" that was once a common plural marker (as still seen in "oxen"). It explains that modern English has largely abandoned this system in favor of adding "-s," but a few relics like "children" and "brethren" survive.
