Ladyboy meaning and where the word comes from
Updated 19 October 2026
On this page
Ladyboy is an English word used mainly in Southeast Asia for trans women and, more loosely, for very feminine people assigned male at birth. It is most closely linked with Thailand, where it translates the Thai words kathoey and sao praphet song. It is informal, widely used and not a slur, but trans woman is the more precise term.
Where the word ladyboy comes from
Ladyboy is a simple compound of lady and boy. It became common in English during the second half of the twentieth century, as tourism to Thailand and neighbouring countries grew and visitors needed a word for the trans women they met. Thai speakers adopted it too, partly because it was easy for foreigners to understand.
The word did not come from medicine or from activist language. It came from everyday speech, travel writing and entertainment. That history explains why it feels casual and why its meaning is a little vague at the edges.
How ladyboy is used in Thailand
In Thailand, ladyboy is mostly the English face of kathoey. Many Thai trans women use it about themselves when speaking English, in social media bios, in work contexts with foreigners and in show business. For them it is a practical word that people understand instantly, and many use it with confidence.
Inside Thai language, the familiar word is kathoey, and the polite word is sao praphet song, often shortened to sao song. We explain the history and tone of the Thai word in detail on our kathoey page.
How ladyboy is used abroad
Outside Southeast Asia, the word has a mixed reputation. It is used:
- In travel guides and media coverage of Thailand.
- By people searching online for Asian trans women, creators or dating sites.
- Sometimes in a mocking way, in comedy or in sensational headlines.
That last use is why some trans women in the West dislike the word. They hear it as a label that treats trans women as a curiosity rather than as women. In Thailand the same word usually sounds far more ordinary.
Ladyboy, kathoey and trans woman side by side
Here is a short way to think about the three terms:
| Term | What it signals |
|---|---|
| Ladyboy | Informal, regional, common in Southeast Asia and in online search |
| Kathoey | Thai word with a long history, familiar inside the community |
| Trans woman | Clear statement of gender identity, respectful in every context |
Ladyboy and kathoey can include people who would not call themselves trans women, such as some feminine gay men. Trans woman refers specifically to someone who identifies as a woman.

When to say trans woman instead
The safe default in English is trans woman. Choose it:
- In formal writing, work settings, medical or legal topics.
- When you speak about a person you do not know well.
- Outside Southeast Asia, where ladyboy is more likely to sound dismissive.
- Whenever a person tells you she prefers it.
Ladyboy is fine in casual conversation in the region and when a woman uses the word herself. In every case, use she and her, and never pair the word with jokes about bodies.
Why LadyBoy.net uses the word
We named the site LadyBoy.net because ladyboy is the word many Thai and Asian trans women and their fans actually use and search for. Inside the site, we use trans women in running text, sao praphet song in Thai, and we treat everyone as a person with a name, a career and a story.
