Horntail

The Hungarian Horntail is a kind of dragon.

How is 'horntail' translated?

角尾龍

jiǎowěi-lóng

The Vietnamese translator uses a similar format, Rồng đuôi gai, with the opposite word order to English or Chinese ('dragon tail thorn').
The Mongolian translation uses эвэр сүүлт ever süült 'horn-tailed'. The final -т -t means 'having', which makes the meaning 'having a horntail'. 'Dragon' is not spelt out.
The Japanese translation is a simple transliteration of the English: ホーンテール hōntēru 'horntail'. This will only make sense to Japanese speakers if they know the words 'horn' and 'tail' in English. 'Dragon' is not spelt out.
The Mainland Chinese translation is something of a mystery. Far-fetched as it might seem, it appears that the translators have somehow got 'horntail' mixed up with 'hornet' (树蜂 shù-fēng 'tree wasp'). The translation does not spell out that the 'horntail' is a kind of dragon.
