Kathoey vs Transgender Female
Kathoey is a specifically Thai word with its own contested, deliberately wide history; transgender female is the plain, internationally used clinical phrase f
The short version
Kathoey (กะเทย) is Thai, belonging to Thailand and Thai people, including those living far from home. Related words exist in Lao and Khmer. Over time it has covered intersex people, trans women, and people who live as women without ever using that word about themselves, and its edges are argued over constantly, in Thai. It's contested even as a word: some use it about themselves without flinching, others prefer สาวประเภทสอง (second-type lady) or ผู้หญิงข้ามเพศ (trans woman), and no one gets to settle that argument for everyone else.
Transgender female is the plain, definitional phrase: a woman who was assigned male at birth. It's the form-filling version of the term — most people say trans woman, trans femme, or just woman, and some find "transgender female" cold because it reads like medical intake paperwork. It carries no specific national or cultural history the way kathoey does, and it's used, and understood, across many countries and languages as a straightforward clinical description.
How to tell them apart
Which one is more likely
More likely Kathoey if…
- You're Thai, or from a Thai family, and the word's specific cultural and linguistic history describes your situation.
- You want a word with an older, wider Thai social history rather than a modern clinical one.
- You're discussing Thailand's specific social and legal context around gender diversity, rather than international definitions.
More likely Transgender Female if…
- You want the plain, internationally understood clinical phrase, useful on forms, in medical settings, or across language barriers.
- You don't have a specific connection to Thai culture or language and want a general description instead.
- You'd rather say trans woman or trans femme day to day, keeping "transgender female" specifically for formal or clinical contexts.
- Both point at women who were not assigned female at birth, though kathoey's boundaries have historically been wider and blurrier than that single definition.
- Neither word is settled or uncontested — kathoey is actively debated within Thai communities, and even transgender female has plenty of people who prefer other everyday phrasing.

What people get wrong
Questions people ask
Can a non-Thai person be called kathoey?
Not really — the word belongs to Thai language and culture. A non-Thai trans woman would generally use trans woman or transgender female instead, since kathoey carries a specific cultural history that doesn't transfer.
Is it offensive to call a Thai trans woman kathoey?
It depends on the person — some use it about themselves comfortably, others find it carries a playground edge and prefer สาวประเภทสอง or ผู้หญิงข้ามเพศ. It's safest to ask, or default to trans woman, rather than assume.
