Is it possible to get origin word and Superlative word from Comparative?

[ByungwooKim-BK]

If I request better, then I hope to get good and best from better.
Is it possible to get origin word and Superlative word from Comparative word?
Request 'Good' :
Response
Superlative: 'best',
Comparative: 'better',
Adverb: 'well',
Noun: 'goodness',
Verb: 'gooden'

Request 'Better'
Response
Superlative: 'betterest',
Comparative: 'betterer',
Adverb: 'betterly',
Noun: 'betterness',
Verb: null

Same way, hope to get origin word and comparative word from Superlative word.
Request 'Best'
Response
Superlative: 'bestest',
Comparative: 'bester',
Adverb: 'best',
Noun: 'bestness',
Verb: 'besten'

Do you have any good idea to get origin word?

hey @ByungwooKim-BK - yes, this is posible with .adjectives().conjugate() - please read the documentation here

console.log(nlp('better').adjectives().conjugate())
/*[
  {
    Adjective: 'good',
    Comparative: 'better',
    Superlative: 'best',
    Noun: 'goodness',
    Adverb: 'well'
  }
]
*/
