What does Schwa mean?
Schwa actually does not have a meaning on its own. It is a collection of letters that forms a sound common in many words.
Schwa is of interest in the field of phonetics and phonology, because it is a specific sound we make when speaking various words. Phonology defines schwa as a mid-central vowel sound.
The sound schwa is originally from Hebrew and was adopted by the German language later. After that, it came to English. It is sometimes spelled as shwa, and by the IPA is marked with the symbol ə.
