English a/an

Determines whether a sequence (noun or adjective) should start with a or an: an elephant, a European, an Irishman, an heir, etc.

It is based on a list of words that must be preceded by an: use english-a-an-list as that list.

Usage

getAAn will return either a or an based on:

• a list custom of exceptions: map where the word is the key, and value has a aan key with either a or an as a value; in general put just null here
• a list of words that must be preceded by an: use english-a-an-list
• the word as a string

Case matters:

• English => an English, while english will not be found
• an AND makes sense, while a/an and doesn't

Installation

npm install english-a-an

Usage

const englishAAn = require('english-a-an');
const englishAAnList = require('english-a-an-list/dist/aan.json');

// an
console.log(englishAAn.getAAn(null, englishAAnList, 'English'));

// a
console.log(englishAAn.getAAn(null, englishAAnList, 'European'));
