I'm sorry, by modifying sed example I meant embedded in your example prints "an an hour." I understand why (2nd statement matching "(a)n" from 1st...so how to fix?
Code:
sed 's/^\<hour\>/an &/; s/^[aeiou]/an &/; s/^[bcdfghjklmnpqrstvwxyz]/a &/ ' test > test2

Thanks for taking the time to demonstrate awk example. I must have been confused before when I ran array ["hour"] and thought I saw the correct result. Just re-tested and indeed it doesn't work. So pipes | are used for complete words.
The pipe symbols in the extended regular expressions used in awk (and grep -E and some other utilities) separate alternatives. They don't have to be complete words. The line of code I suggested:
Code:
/^(heirs|honors|hours)/{print "the " $0; next}
could also be written as:
Code:
/^h(eir|onor|our)s/{print "the " $0; next}
(which looks for the letter "h" at the start of a line followed by one of the strings "eir", "onor", or "our" followed by the letter "s") and get exactly the same results with less typing. I just find the first form easier for many of the novices who read this forum to understand. (And the longer form keeps automatic spell checkers from trying to correct non-existent typos. )

Locale::Codes::LangExt(3pm) Perl Programmers Reference Guide Locale::Codes::LangExt(3pm)NAME
Locale::Codes::LangExt - standard codes for language extension identification
SYNOPSIS
use Locale::Codes::LangExt;
$lext = code2langext('acm'); # $lext gets 'Mesopotamian Arabic'
$code = langext2code('Mesopotamian Arabic'); # $code gets 'acm'
@codes = all_langext_codes();
@names = all_langext_names();
DESCRIPTION
The "Locale::Codes::LangExt" module provides access to standard codes used for identifying language extensions, such as those as defined in
the IANA language registry.
Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default IANA language
registry codes will be used.
SUPPORTED CODE SETS
There are several different code sets you can use for identifying language extensions. A code set may be specified using either a name, or
a constant that is automatically exported by this module.
For example, the two are equivalent:
$lext = code2langext('acm','alpha');
$lext = code2langext('acm',LOCALE_LANGEXT_ALPHA);
The codesets currently supported are:
alpha
This is the set of three-letter (lowercase) codes from the IANA language registry, such as 'acm' for Mesopotamian Arabic.
This is the default code set.
ROUTINES
code2langext ( CODE [,CODESET] )
langext2code ( NAME [,CODESET] )
langext_code2code ( CODE ,CODESET ,CODESET2 )
all_langext_codes ( [CODESET] )
all_langext_names ( [CODESET] )
Locale::Codes::LangExt::rename_langext ( CODE ,NEW_NAME [,CODESET] )
Locale::Codes::LangExt::add_langext ( CODE ,NAME [,CODESET] )
Locale::Codes::LangExt::delete_langext ( CODE [,CODESET] )
Locale::Codes::LangExt::add_langext_alias ( NAME ,NEW_NAME )
Locale::Codes::LangExt::delete_langext_alias ( NAME )
Locale::Codes::LangExt::rename_langext_code ( CODE ,NEW_CODE [,CODESET] )
Locale::Codes::LangExt::add_langext_code_alias ( CODE ,NEW_CODE [,CODESET] )
Locale::Codes::LangExt::delete_langext_code_alias ( CODE [,CODESET] )
These routines are all documented in the Locale::Codes::API man page.
