If you say that you are going to tell someone something in words of one syllable, you mean that you are going to say it as simply and clearly as possible.

Examples: ... Could you explain to me in words of one syllable how an electron microscope works? (СALD)
... Surely there should be a book somewhere explaining all this stuff in words of one syllable for otherwise intelligent adults like me.

You often use this expression to suggest that the other person is stupid or slow to understand something.

Examples:
...I'm sure I don't have to spell things out in words of one syllable to you.
