Atertiary, also known as nontertiary, is an identity defined by a complete lack of tertiary attraction. One who is atertiary would not experience any form of tertiary attraction, and would by default be nonamical, asocial, amental, nonparental, etc.
Atertiary indiviuals may still engage in activities traditionally defined by tertiary attraction, such as having tertiary relationships.
Someone who experiences little, fluctuating, or atypical tertiary attraction or someone who only experiences certain types of tertiary attraction would be considered on the atertiary spectrum (ater spec).

The term was coined by Tumblr user mourningmogaicrew on June 4th, 2021 to help a-spec individuals describe themselves. Similar terms and experiences have been described by a-spec individuals in the past, especially on forums such as AVEN.
Controversy around the term tertiary attraction
The term tertiary attraction is occasionally criticized for meaning "third" and implying tertiary attractions are not as important as other forms of attraction. The term eriattraction has been suggested as an alternative. Someone who doesn't experience eriattraction may consider themself nonerittracted.
