An affix is a morpheme that is added (affixed) to a root word to change its meaning. Prefixes and suffixes are both types of affixes. A prefix is an affix that occurs before the root word, while an affix attached at the end is a suffix.[1] The addition of prefixes or suffixes creates another orientation term.[2]


Gender(s) attracted to or experienced[]

Prefix Meaning Details
homo- attracted to the same gender as one's own[3][2] The literal meaning of hom- is "one and the same; similar; alike".[4] See: gay (aka homosexual) and homoromantic
attracted to similar gender(s) as one's own[3] Inclusive of a range of non-binary genders that are not the "same" but have similarities.[3]
hetero- attracted to the other binary gender[3] or a gender that is not one's own gender[2] Often defined as directed toward the "opposite" gender due to how the gender binary views men and women.[3] See: heterosexual and heteroromantic
bi- (as a gender term) two genders[3] As a gender term, refers to having or experiencing two different genders. See: bigender[3]
(as an attraction term) having the potential to be attracted to more than one sex or gender;[5] being attracted to people of a gender like one's own and different from one's own[6] Not necessarily limited to the gender binary.[7] Bi people do not always experience their attractions to different genders equally or in the same way.[3] Bi- and pan- may be used interchangeably by some people and usage of both or one is personal preference;[8] some consider bi to be an umbrella term that encompasses pan.[6] See: bisexual and biromantic
tri- three genders[3]
multi- multiple genders (but not necessarily all)[3] When used regarding gender, multi- and poly- can both be used to indicate a person who identifies as more than one gender.[3] However, multigender is generally used as an umbrella term for labels where a person is more than one gender at a time, with polygender being under that umbrella.[9] Multisexual is an individual label and an umbrella term for other sexual orientations that include attraction to more than one gender, including polysexual.[3] See: polyromantic and polyamorous
omni- any / all genders[3] When used regarding attractions, omni- indicates that the gender of the object of attraction does have an effect on the way that attraction is experienced,[3] according to definitions of bi- vs. omni- vs. pan- labels that treat each as separate and distinct. See: omnisexual and omniromantic
pan- When used regarding attractions, pan- indicates that the gender of the object of attraction does not have an effect on the way that attraction is experienced,[3] according to definitions of bi- vs. omni- vs. pan- labels that treat each as separate and distinct. See: pansexual, panromantic, and pangender (aka omnigender)
cetero- attracted to non-binary genders[2][3][10] Cetero- replaced skolio-,[2] but opinions differ over whether only non-binary and transgender people should use the term,[3] with some asserting the limitation as a fact.[2][10] See: ceterosexual and ceteroromantic


Due to skolio- meaning "bent" or "broken" and implying a need to be fixed, it has been replaced by cetero-.[2]
