A vowel combined with a sheva.
- KHW calls them “composite shevas”.
- This grammar classifies them as “half vowels”.
- Others refer to them as “reduced vowels” (as here) or “very short vowels”.
- This video calls them “compound shewas”.
- This chart uses the word chateph-patah, chateph-qamats, etc. and classifies them as “reduced vowels”.
These are all different names for the same reality.
