What Are 12 Letter Words?

As the name would suggest, words with 12 letters in their spelling are called 12-letter words. These words range in how common they may be when it comes to usage and sound but they are all difficult to learn at first. For example, Bacchanalian sounds like some alien planet that was just recently discovered but in reality, it means, “Characterized by or involving drunken revelry”. If someone is drunk and is partaking in lively festivities then they are being bacchanalian.

A cabinetmaker is an easy-to-remember 12-letter word that is a job. If someone gets paid to make cabinets then they are a cabinetmaker.

A fabrication is something that is created, often attributed to falsehoods.
