🔧 Extending Rules

Since verbalizer is an actual instance of Verbalizer, you can extend or modify it at runtime:

// Add a custom base rule
verbalizer.addBaseRule(/ied$/i, 'y');

// Add a custom past tense rule
verbalizer.addPastRule(/e$/i, 'ed');

// Add a custom past participle rule
verbalizer.addParticipleRule(/e$/i, 'ed');

// Add an irregular verb
verbalizer.addIrregular('swim', 'swam', 'swum');

These modifications affect all consumers of the shared instance.

🏗 Need your own configuration?

If you want an isolated instance with its own rules, instantiate the class directly:

import { Verbalizer } from 'nhb-toolbox';

const myVerbalizer = new Verbalizer();
myVerbalizer.addIrregular('dream', 'dreamt', 'dreamt');
console.log(myVerbalizer.toPast('dream')); // dreamt
