In The Loom of Language: An Approach to the Mastery of Many Languages, the the author, Frederick Bodmer, argues that the third-person present conjugation (of regular verbs) in English serves no purpose and that it should be eliminated for the hypothetical aim of making English into a more logical and easier-to-learn language.
To understand what Bodmer was talking about, let us see the following conjugation table for the verb ‘to eat’ in the simple present tense.
Among the 6 conjugations, 5 of them are in the form of ‘eat’. In a more logical world, the following table may be true.
Now, 6 of the 6 forms are of the form ‘eat’. Bodmer argues that the s ending serves no purpose since English is not a pro-drop language. No information is lost if we do not pronounced the s, and speakers of English will still understand us. English is a pro-drop language in informal settings.
e.g. — ‘Where you going?’
— ‘Going to the store.’
While Bodmer’s example is a not a realistic option for English, it is a useful case study for constructed languages.
