Support plan

• which support plan is this issue covered by? (e.g. Community, Core, Plus, or Enterprise): community
• is this issue currently blocking your project? (yes/no): no
• is this issue affecting a production system? (yes/no): ? -- the output impacts anyone who uses a number of different validation mechanisms, validation still happens, but the reporting is grammatically poor.

Context

• node version: any
• module version with issue: dbde086
• last module version without issue: 6a267f2 (for everything except dates)
• environment (e.g. node, browser, native): all
• used with (e.g. hapi application, another framework, standalone, ...): any
• any other relevant information: I think I first spotted this in some random project, and then I just browsed the source. I'm reporting this as an issue because your PR guidelines suggest that I shouldn't create a PR first.

What are you trying to achieve or the steps to reproduce?

'use strict';

const Code = require('@hapi/code');
const Joi = require('..'); /* yes, this is stolen from test/base.js */
const Lab = require('@hapi/lab');

const { describe, it } = exports.lab = Lab.script();
const { expect } = Code;
    describe('placeholder', () => {
            it('should have proper English grammar', () => {

                const schema = Joi.object({
                        c: Joi.number().min(0).integer().strict().error((errors) => {

                            return new Error(errors.join(' and ')); // Automatic toString() of each error on join
                        })
                });

                const err = schema.validate({ c: -1 }, { abortEarly: false }).error;
                expect(err.message).to.equal('"c" must be greater than or equal to 0');
            });
    });

What was the result you got?

'"c" must be larger than or equal to 0'

What result did you expect?

'"c" must be greater than or equal to 0'
