When selecting a name for a private limited company, it is important to ensure that the name is not already in use by another company and that it does not infringe on any trademarks or service marks. Additionally, the name should be consistent with the company's business and should not contain any restricted or sensitive words.
Examples of restricted or sensitive words that should not be included in a company name are: "National", "Government", "Engineer", "University", "Charity", "Trust", racial slurs or profanity. However, it is important to check with the relevant government registrar of companies for a comprehensive list of restricted words in your area.
