I really can't find it out.
Please tell me the difference of them.
Thanks in advance!
'ə' (schwa) = the shortest vowel sound in English; sounds a bit as if you were lifting something heavy and let out air. ALWAYS UNSTRESSED, and as a rule doesn't appear in 1-syllable content words (nouns, verbs, adjectives, adverbs). Practically any vowel (a, e, i, o, u) may be pronounced as a schwa. For example, it can be heard in words like "doctor", "again", "sharpen" ....etc
'ʌ' (short a) = it's also a short sound, but it is usually stressed, or appears in one-syllable words. It is usually represented by letters "u" and "o" ("son", "sun", "come", "begun", "fun", ....etc), but there are also some exceptions ("blood" and "flood", for example).
Correction:
"I really don't know. / I really don't get it. Please tell me how to tell them apart"
