7. Words that have the Schwa + R sound: A SCHWA is the name of a vowel sound and of the linguistic symbol used to denote that sound. The symbol is an upside-down small printed "e" , sometimes with a colon (:) after it, and the sound it represents is a middle-of-the-mouth, nothing special one, the sound you might make as you try to think of what to say next.  In writing, this sound might be represented like this: "Uhh."  The schwa sound is very common in English words.  Here are several examples. In all the one-syllable words, the vowel will sound like a Schwa, while in the multi-syllable words, the red letters will sound like a schwa.  Notice that each of the letters U, E, O, OU and A  are used to make the SCHWA sound in various words.

NOTE: I had to check many of these words in the dictionary to be sure they really did contain the SCHWA sound.  You can do that, also.  Somewhere in the dictionary will be a guide to  the various linguistic symbols used and what sounds they stand for, and in the body of the dictionary, after each word, you should find the symbols used to describe how each word is pronounced.

8.  Words that have the -ANK, -INK, -ONK, or -UNK sounds: Words that have the same letter combinations will sound the same, so if you know what one word sounds like, you will be able to pronounce the other words that are spelled with the same letters.
