Ah the dangers of Google translate and synonyms. You got the wrong definition for right when translating to Irish, the one you have means correct, deis is the word for right (direction). Clé is left, the h appears in certain contexts for grammatical reasons.
Sorta the concept behind Twisted Translations, previously known as Google Translate Sings. Though they are intentionally getting a bad result by feeding the Translations through several languages before coming back to English.
Amazingly, the Dutch version of SharePoint has made this mistake. There is an option, I believe when making columns on a page or something, for "Links" (left) and "Goed" (right/correct).
Chinese is also not right - 正确的 (zhèngquè de) means "proper"
Left and Right as the sides are 左 (zuǒ) and 右 (yòu) - you can also add 邊 (biān) to each which means "side" to be more explicit, but they are also used separately in many contexts where the left/right meaning is needed.
The Chinese characters for 左 and 右 actually originated as pictograms of the left and right hand in the early forms of Chinese writing, but later forms both contain general "hand" component (𠂇) with components 工 and 口 added for differentiation
