Many foreign speakers have trouble with word endings.  The “ING” ending is commonly used.  I hear foreign speakers pronounce the “ING” as:  “INK”, “IN”, “ENG”, “EENG” or “IN GA”.

When mispronounced, the word sing would sound like sink, sin, seng or sin ga (which might be interpreted as singer).  When “ING” is added to a verb to change the tense, the word thinking would sound like thinkin or thinkeeng.

To correct this error, do these things:

  1. make the vowel short
  2. make the NG one sound
  3. say NG not N.  Do this by touching the tip of the tongue to the back of the bottom, front teeth; NOT the top teeth.

Good luck!  People will notice a difference.
