The tengwar modes services are a set of rules and conventions for writing tengwar. They were developed by J.R.R. Tolkien and first published in The Lord of the Rings. The modes services are not mandatory, but they are recommended for those who want to write tengwar in a consistent and legible way. There are four modes services: the Quenya mode, the Sindarin mode, the Telerin mode, and the Doriathrin mode. Each mode has its own set of rules and conventions.
There are two main types of tengwar modes: Quenya and Sindarin. Each mode has its own set of rules and services. Quenya is the most common mode, and is used for writing in Quenya, the language of the elves. Sindarin is used for writing in Sindarin, the language of the dwarves. There are also a few other less common modes, such as Beleriandic and Noldorin.
Overall, the tengwar modes services provide a great way for people to learn more about the different modes of the tengwar writing system. The services are affordable and the team is very knowledgeable. If you're looking for a way to improve your tengwar skills, or if you're just curious about the different modes of the tengwar, I highly recommend checking out the tengwar modes services.
