Homographs: different meaning and different pronunciation

Homographs are words that have the same spelling, but the meaning and pronunciations are different.  These are VERY difficult for most ESL speakers.

For example:

CLOSE

Close (pronounced CLOZ) the door.

Don’t stand so close (pronounced CLOS) to me.

PROJECT

The project (pronounced praw ject) is difficult.

Please project (pronounced pro ject) your voice.
