What happened to the “-est” and “-eth” verb suffixes in English? How were they once used?
How do you conjugate Early Modern English verbs (other than present tense)?
In all the languages I know about, including German - the cousin of the English language, all the verbs use different suffixes for conjugation. English uses a far simpler conjugation method (only add s for he/she) and has some irregular verbs.
My questions are:
Are there other languages with similar grammar for conjugation?
How this special feature of the language came to light? Is there info about the time/way/reasons it was formed?
