In German it is necessary to distinguish the sounds r, ɐ, l , especially when they are occure at the end of the word. Otherwise it would be hard for example to distinguish between “vier” (four) and “viel” (much), words, which are used in basic conversation in German.
The sound [ɐ] is called a near-open central vowel and occurs expecially when you pronounce words written with an “-er” at the end like:
The pronunciation of [ə] sounds similar, but it is important to distinguish it from the [ɐ]. [ə] is a mid-central vowel and occures in words like:
Also words ending with a written “-el” or “-en” are not pronunced exactly like the writing suggests: Mostly the “e” is not pronunced, for example in words like:
Read the words aloud again and again with your tutor to become familiar with the differences!
