RE explanation

Could someone give me an explanation for each part of this regular
expression ?

/\b((??=[a-z])[^aeiou])*[aeiou](??=[a-z])[^aeiou])*)\b/ig

Many thanks

Why? I'd suggest that you look it up at first hand:

perldoc perlre

and ask a question if there is anything specific you can't figure out
that way.

It seems to match words which contain exactly one vowel.

See perldoc perlre.

Doesn't the letter 'y' also count as a vowel in English? (In Swedish it
does.)

Yes! Well, maybe.. Hm, maybe not..

Oh, bother. :-/

It does. But also a consonant.

But then most English people are brought up with the myth of five
vowels.
