When using a pattern for validation purposes, you usually need to add start and end of string placeholders (^ and $) to ensure no additional characters exist before or after the characters matched by the pattern.

eg the pattern ab?d would match the value abcde but pattern ^ab?d$ would not match it.

So for 3 words separated by a space character you might want to try pattern:

^\w+ \w+ \w+$

yes but it run with English  character only no different  language

Then you could use this:

^[a-zA-Z]+ [a-zA-Z]+ [a-zA-Z]+$

Select allOpen in new window

Or the same thing, but shorter:

^([a-zA-Z]+ ){2}[a-zA-Z]+$

Select allOpen in new window

it also work with English letter

Sorry, you'll need to better explain what the problem is.
