This is why it sometimes seems like they're unnatural to read, because the very specific English word that is a direct translation doesn't exist in the set of allowed words, so they need to find a different way of saying it.
The spelling of the y-shaped LPTACC & HPTACC supply duct on the LEAP-1A in the AIB manuals is a personal favourite - the "wye" duct / Ross-on-Wye duct.
