I feel such a fool for not being able to work this out, but..
What do I to
llSay(0, "Hello " + llDetectedName(0));
to get it to say, "Hello Innula" rather than "Hello Innula Zenovka" ?

string name = llDetectedName(0);
llSay(0, "Hello " + llGetSubString(name, 0, llSubStringIndex(name, " ") - 1));

...and for the programming novice...

an explanation:
llGetSubString takes a string, a start position, and an end position. It cretes a new string that is the substring of the first. See the WIKI for details.
In this case, start at 0 (not 1) and go as far as the first blank minus 1. llStringIndex finds the count of the first " ".
Can first names have " "'s in them? I don't think last names can have blanks, so maybe you should search for " " from the end of the string instead of the beginning.

No, you can't have spaces in a firstname.
As a more general tip for finding words in a string, the original poster might wish to take a look at llParseString2List. For instance
list words = llParseString2List(message, [" ", ",", ".", "-", ";", ":"], []);
will give you a list of strings which comprise the words in a particular string message, splitting them out by the series of characters in the second parameter. There is also llParseStringKeepNulls which operates in the same way but, as the name suggests, also allows for null elements, and which is sometimes more useful for parsing command strings as opposed to speech.

Thanks, both. I thought it must be something to do with llGetSubString but I didn't understand how to extract the first word and was getting completely confused trying to find the space between the first and second names and work back from there.. .You have been a huge help.

Using Ordinal's method is quite acceptable as well:
llSay(0, "Hello " + llList2String(llParseString2List(llDetectedName(0), [" "], []), 0));
