OSTIAL/OSTEAL
Many a times, I have come across this error. This simple confusion can be avoided if we
try to remember where to use which one.
I will just try to explain as these two different spellings with same
pronunciation will lead to a critical major error and often goes unnoticed,
i.e., silly mistake.
OSTIAL: This
means related to ostia or an or-I-fice or a small opening.
OSTEAL: This means related to ossEous or bone.
BOTTOM LINE
The best way to remember is quite simple. The I of OSTIAL denotes the I of ORIFICE.
The same goes with ostium.
