TLD: Top Level Domain - A domain extension which forms the part of a domain name that appears after the last dot. Example: The TLD for quadletterdomains.com is ‘.com’.
ccTLD: Country Code Top Level Domain - Typically a two letter domain extension that corresponds to a country, territory or geographic location. Example: The ccTLD for ‘quadletterdomains.co.uk’ is ‘.co.uk’.
LLLL.TLD: A domain consisting of four letters whereby the ‘L’ stands for ‘Letter’ and you replace ‘TLD’ with the appropriate extension. Example: ‘QLDZ.com’ is a ’LLLL.com’.
CCCC.TLD: A domain consisting of four characters whereby the ‘C’ stands for ‘Character’ and you replace ‘TLD’ with the appropriate extension. It can be a combination of letters, numbers or hyphens. Example: ‘Q-L3.com’ is a ‘CCCC.com’. Many people confuse these types of domains with four letter domains.
NNNN.TLD: A domain consisting of four numbers whereby the ‘N’ stands for ‘Number’ and you replace ‘TLD’ with the appropriate extension. Example: ‘0297.com’ is a ‘NNNN.com’.
Is is possible to use a mixture of the above to form a letter combination that better defines a specific domain. Example: ‘2T5P.com’ is a ‘NLNL.com’. However, this type of definition is more commonly seen in domain shorter than four characters.
It is possible to further sub categorise four letter domains using the following letter combinations:
Consonant, vowel configurations can include, CVCV, VCVC, VCCV, CVVC whereby ‘C = Consonant’ and ‘V = Vowel’. Depending on the placement of letter types, certain combinations are deemed more desirable because they can be pronounced.
CVCV: Example: ‘SEDO.com’
VCVC: Example: ‘ODES.com’
CVVC: Example: ‘SOED.com’
VCCV: Example: ‘OSDE. com’
The inclusion of a ‘Y’ within a four letter domain gives the ability to pronounce it under certain circumstances. To define a four letter domain containing a ‘Y’ you replace the ‘V’ in a letter pattern with a ‘Y’. Example: SEDY.com is a CVCY combination.
VVVV.TLD: A domain consisting of four letters whereby the ‘V’ stands for ‘Vowel’ and you replace ‘TLD’ with the appropriate extension. Example: ‘AEIO.com’ is a ’VVVV.com’.
Repeating Letter Patterns:
Repeating letter domains are generally higher priced than other domains that have four unique letters. For this reason many people further sub categorise their quad letter domains into groups by repeating letter patterns. Example: ‘POPO.com’ is a CVCV but can be further sub categorised as an ABAB whereby A = The first repeating letter and B = The second repeating letter.
ABAB: Example: ‘POPO.com’
ABBA: Example: ‘OPPO.com’
AABB: Example: ’OOPP.com’
Other general terms you may come across include:
Palindrome: A word, phrase, verse, or sentence that reads the same backwards as it does forward. Example: ‘racecar’ or ’RTTR.com’.
